Moving to the USA requires choosing a visa category first, then following the process for that specific visa type

There is no single "migration visa" to the USA. Instead, you pick a visa category based on your situation — whether you have a job offer, family in the country, investment capital, or another may have access to circumstance. Each category has its own requirements, processing timeline, and rules about what you can do once you arrive. The visa itself is just the entry document; what happens after you land depends on which visa you used to get there.

The most common paths are employment-based visas (like the H-1B for specialty occupations), family-sponsored visas, diversity visas, and investor visas. Some people enter on a temporary visa first — a student visa or tourist visa — and then change status to an immigrant visa later. Others explore directly for permanent residency. Understanding which category fits your situation is the first decision, because it determines every step that follows.

Key Takeaways

  • You must may have access to for a specific visa category; there is no general "migration" visa that works for everyone.
  • Employment visas require a US employer to sponsor you, family visas require a relative to petition for you, and diversity visas are allocated by lottery to nationals of countries with low immigration to the USA.
  • Processing times vary from a few months to several years depending on the visa type and your country of origin.
  • A visa gets you into the country, but your ability to work, stay long-term, and bring family members depends on which visa category you used.
  • The US State Department and USCIS (US Citizenship and Immigration Services) handle different parts of the process, and you will need to work with both.

Employment-Based Visas: When a US Employer Sponsors You

An employment visa requires a US employer to sponsor you. The employer must file a petition with USCIS (US Citizenship and Immigration Services) showing that they want to hire you and that no US worker is available for the job. The most common employment visa is the H-1B, which is for specialty occupations — typically roles requiring a bachelor's degree or higher in fields like technology, engineering, accounting, and healthcare.

The H-1B process starts with your employer filing a petition, usually in early April for a visa that begins in October. USCIS receives far more petitions than visas available, so they conduct a lottery. If your petition is selected, USCIS approves it, and you can then explore for the visa at a US embassy or consulate in your home country. The entire process typically takes four to six months from petition to visa approval, though the lottery itself means you may not be selected at all.

Other employment visas include the L-1 (for employees transferring within a company), the O-1 (for people with extraordinary ability in their field), and the EB-3 (permanent residency for skilled workers, which takes longer but leads to a green card). Each has different requirements and timelines. An immigration attorney can help you and your employer understand which visa fits your situation.

Family-Sponsored Visas: When a US Relative Petitions for You

If you have a close relative who is a US citizen or permanent resident, they can petition for you. The relationship must be when ready family (spouse, parent, or child under 21) or, in some cases, a sibling or adult child. Your relative files Form I-130 (Petition for Alien Relative) with USCIS. Once approved, you can explore for an immigrant visa, which leads to a green card.

Processing times for family visas vary widely. when ready relatives of US citizens (spouse, parent, child under 21) typically wait one to two years. Other family relationships face longer backlogs — sometimes five to ten years or more — because Congress limits the number of family visas issued each year. You can check current wait times on the State Department's visa bulletin, which updates monthly and shows how far back applications are being processed.

Your relative must also show they earn enough to support you financially. They file an Affidavit of Support (Form I-864) proving their income is at least 125 percent of the federal poverty line for their household size. If they do not earn enough, they can find a co-sponsor — another US citizen or permanent resident who agrees to take financial responsibility for you.

Diversity Visas: The Lottery for Nationals of Underrepresented Countries

The US runs an annual diversity visa lottery, also called the DV lottery, which makes 55,000 visas available to nationals of countries that have sent fewer than 50,000 immigrants to the USA in the previous five years. Most European countries, Canada, Australia, and New Zealand are excluded because they already send many immigrants. Many African, Central Asian, and Pacific Island nations are included.

The lottery opens for registration once a year, usually in October, for a two-week window. You register online for free on the State Department's website. If your name is drawn, you are notified by email, and you then explore for an immigrant visa. The entire process, from registration to visa approval, typically takes one to two years.

To enter, you must have a high school diploma or equivalent, or two years of work experience in an occupation that requires at least two years of training. You also must pass a medical exam and background check. The odds of being selected are low — millions of people enter each year for 55,000 visas — but the cost is zero, and there is no employer or family member required.

Student and Temporary Visas: Entering First, Changing Status Later

Some people move to the USA on a temporary visa first — such as an F-1 student visa or a B-1/B-2 tourist visa — and then change their status to an immigrant visa or work visa later. A student visa lets you study at a US college or university and work on campus. After graduation, you may be able to stay for Optional Practical Training (OPT), which allows you to work in your field for up to three years.

If you find an employer willing to sponsor you while on OPT, they can file an H-1B petition for you. If you have a family member or employer willing to sponsor you for permanent residency, you can explore to change your status from student to immigrant without leaving the country. This path takes longer overall but allows you to work and study in the USA while your permanent residency process is being processed.

A tourist visa (B-1/B-2) does not allow you to work, but it does let you enter the country. Some people use this to attend interviews for employment visas or to visit family while their visa petition is pending. You cannot change status from a tourist visa to a work visa directly, but you can leave the country and re-enter on a work visa once it is approved.

The Medical Exam, Background Check, and Visa Interview

Once your visa petition is approved by USCIS, you must complete a medical exam with a doctor approved by the US State Department. The exam checks for communicable diseases and certain health conditions. You also undergo a background check, which includes fingerprinting and a review of your criminal history. These steps are required for all immigrant visas and most temporary work visas.

After the medical exam and background check, you attend an interview at a US embassy or consulate in your home country. A consular officer reviews your petition, your documents, and your answers to questions about your background, your job, and your ties to your home country. The interview typically lasts 10 to 20 minutes. The officer decides whether to approve or deny your visa on the spot, though some cases require additional review.

Bring original documents to the interview: your passport, birth certificate, marriage certificate (if applicable), police clearance, medical exam results, and any documents related to your visa petition. Have copies as well. If documents are in another language, bring certified translations. The consulate will tell you exactly what to bring when they schedule your interview.

After You Arrive: Work Authorization and Green Cards

What you can do once you land depends on which visa you used. If you arrived on an H-1B, you can work for the employer who sponsored you. If you arrived on an F-1 student visa, you can work on campus or in an approved off-campus position. If you arrived on an immigrant visa, you can work for any employer — you do not need sponsorship.

If you arrived on an immigrant visa, you are on the path to permanent residency. You will receive a green card (Permanent Resident Card) in the mail within a few weeks. A green card lets you live and work anywhere in the USA, travel outside the country and return, and sponsor family members. After five years as a permanent resident (or three years if you are married to a US citizen), you can explore for US citizenship.

If you arrived on a temporary work visa like the H-1B, you can stay as long as your visa is valid and your employer continues to sponsor you. To become a permanent resident, your employer must file an employment-based green card petition for you. This is a separate process from the H-1B visa and can take several years. During this time, you can remain in the USA on your H-1B visa while your green card process is pending.

Processing Times and What to Expect

Visa processing times vary dramatically. An H-1B petition takes four to six months from filing to approval. A family visa for an when ready relative takes one to two years. A family visa for a sibling or adult child can take five to ten years or longer. A diversity visa takes one to two years from the lottery draw to visa approval. An employment-based green card can take anywhere from two to ten years depending on your country of origin and your job category.

Processing times also depend on your country of origin. Nationals of countries with high immigration to the USA — particularly Mexico, Philippines, India, and China — face longer waits for family and employment visas because Congress allocates visas by country. You can check current processing times on the USCIS website and the State Department's visa bulletin.

During the waiting period, you can remain in the USA if you are on a valid temporary visa. You can also travel outside the country and return, though you must have the proper documents. An immigration attorney can advise you on whether you can travel safely while your process is pending.

Frequently Asked Questions

Can I move to the USA without a job offer or family member?

Yes, through the diversity visa lottery if your country is included, or if you have investment capital for an EB-5 investor visa. The EB-5 requires you to invest at least $1,050,000 (or $800,000 in a rural or high-unemployment area) in a business that creates at least 10 jobs. Processing takes several years. The diversity lottery is free but has very low odds.

How long does it take to get a green card?

It depends on your visa category and country of origin. when ready relatives of US citizens typically wait one to two years. Other family relationships wait five to ten years or longer. Employment-based green cards take two to ten years. Diversity visas take one to two years. Check the State Department's visa bulletin for your specific category and country.

Can I bring my spouse and children with me?

Yes, but the process depends on your visa type. If you are on an H-1B, your spouse can come on an H-4 visa, but they cannot work unless they have their own work visa. Your children can come on H-4 visas. If you are on an immigrant visa, your spouse and children can come with you or join you later. An immigration attorney can explain the options for your situation.

What happens if my visa is denied?

You can reapply, but you must address the reason for the denial. Common reasons include insufficient documentation, concerns about your ties to your home country, or criminal history. The consular officer will tell you why you were denied. You can request a new interview after gathering additional documents or after circumstances change.

Do I need an immigration attorney?

You can file some visa petitions without an attorney, but immigration law is complex and mistakes can delay your case or result in denial. An attorney can review your documents, help you gather evidence, and represent you at interviews. Many offer free initial consultations. If cost is a concern, some nonprofits offer low-cost immigration legal services.
