What a US visa actually lets you do

A US visa is permission to enter the country and stay for a specific purpose — but the visa type itself determines what you are allowed to do once you are here. The visa does not give you blanket rights to work, study, or live anywhere you choose. Instead, each visa category comes with rules about employment, education, travel, and how long you can remain.

The most common mistake is assuming that any US visa lets you work. It does not. A tourist visa (B-2) explicitly forbids employment. A student visa (F-1) allows you to study but restricts work to campus jobs and certain internships. A work visa (H-1B, L-1, O-1) permits employment only with the sponsoring employer and only in the role described in your petition. Violating these restrictions can result in deportation and a ban on future entry.

Key Takeaways

  • Tourist visas (B-1/B-2) do not permit any form of paid or unpaid work, including remote work for a foreign company.
  • Student visas (F-1) allow on-campus employment up to 20 hours per week during school and full-time during breaks, plus optional practical training after graduation.
  • Work visas (H-1B, L-1, O-1, EB visas) permit employment only with the employer who sponsored your visa and only in the position described in the petition.
  • Changing your visa purpose — such as switching from tourist to student status — requires filing a new petition and waiting for approval before you change your activities.
  • Overstaying your visa or working without authorization can result in deportation, a 3- to 10-year bar on re-entry, and a permanent mark on your immigration record.

Tourist and visitor visas do not cover work

If you hold a B-1 (business visitor) or B-2 (tourist) visa, you cannot work in the United States under any circumstances. This includes paid employment, unpaid internships, volunteer work, and remote work for a foreign employer. The visa is issued specifically for tourism, visiting family, attending conferences, or conducting business meetings — not for earning income.

Many people assume that remote work — working for a company outside the US while physically in America — is permitted because the employer is not American. It is not. US immigration law prohibits any work activity, regardless of where your employer is located or whether you are paid in US dollars. If you are caught working on a tourist visa, you can be deported when ready and barred from returning for 3 to 10 years.

Student visas allow limited work and study-related employment

An F-1 student visa permits you to study full-time at an accredited US school, but employment is restricted. You can work on campus — in the library, dining hall, administrative offices, or other school facilities — up to 20 hours per week while classes are in session. During official school breaks and summer, you can work full-time on campus.

Off-campus work is possible but requires prior approval from your school's international student office. Curricular Practical Training (CPT) allows you to work off-campus in a job directly related to your field of study, but only if your school approves it as part of your curriculum. Optional Practical Training (OPT) is available after you graduate and allows you to work in your field for up to 12 months (or 24 months for STEM degrees). All of these require documentation from your school before you begin work.

Work visas tie you to a specific employer and job

An H-1B visa, L-1 visa, O-1 visa, or employment-based green card (EB-1, EB-2, EB-3) permits you to work in the United States, but only for the employer who sponsored your visa and only in the position described in your petition. If your petition says you will work as a software engineer for Company A, you cannot switch to a marketing role at Company B without filing a new petition and waiting for approval.

Changing employers requires your new employer to file a new visa petition on your behalf. During the time between jobs, you may be out of status if you do not have a valid work authorization document. Some visa categories allow you to start working with a new employer while the petition is pending (called "portability"), but this depends on the visa type and your specific circumstances. You should always consult an immigration attorney before changing jobs to avoid losing your status.

Switching your visa purpose requires a new petition

If you arrive on a tourist visa and later decide you want to study or work, you cannot straightforward change your activities. You must file a new petition for the appropriate visa category (F-1 for students, H-1B or other work visa for employment) and wait for approval before you change your status. Changing your activities without filing a new petition puts you out of status and can result in deportation.

Some visa categories allow you to change status while in the United States without leaving and re-entering. Others require you to leave the country, explore at a US embassy or consulate, and return with the new visa. The rules vary by visa type and your country of citizenship. An immigration attorney can advise you on the fastest and safest route for your situation.

What happens if you work without authorization

Working without a valid visa or work authorization is a federal violation. If you are discovered, you will be placed in removal proceedings and deported. You will also be barred from returning to the United States for 3 to 10 years, depending on how long you worked without authorization. This bar applies even if you later marry a US citizen or receive a job offer — you must wait out the full period before you can return.

Additionally, working without authorization creates a permanent record that affects all future visa and immigration decisions. Even after the bar expires, consulates and immigration officers will see the violation on your file. Employers who knowingly hire workers without authorization also face fines and penalties, so many will ask for proof of work authorization before hiring you.

Visa status and travel outside the United States

Your visa is your permission to enter the United States. Once you are inside the country, your status is what matters. If you leave the US and want to return, you need a valid visa in your passport. If your visa has expired, you will need to explore for a new one at a US embassy or consulate before you can re-enter.

Some visa categories allow you to travel outside the US and return without losing your status, as long as your visa is still valid. Others require you to maintain continuous presence in the country. If you are on an F-1 student visa, you can travel abroad during breaks and return as long as your school has authorized your travel and your visa is valid. If you are on an H-1B work visa, you can travel for business or personal reasons and return, but you must have a valid visa stamp to re-enter. Always check with your visa sponsor or an immigration attorney before traveling internationally.

Frequently Asked Questions

Can I work remotely for my home country company while on a US tourist visa?

No. US immigration law prohibits any work activity on a tourist visa, including remote work for a foreign employer. The location of your employer does not matter — if you are performing work while physically in the United States, you are violating your visa terms. This can result in deportation and a 3- to 10-year bar on re-entry.

Can I switch from a student visa to a work visa without leaving the country?

Yes, in most cases. You can change status from F-1 to an employment-based visa (such as H-1B) while in the United States if your employer files the petition and it is approved before your student status expires. However, you cannot work in the new job until the petition is approved. An immigration attorney can advise you on timing and whether you need to leave the country for visa stamping.

What if I overstay my visa by a few days?

Even a few days of overstay creates a record and can affect future visa decisions. Overstays of 180 days or more trigger a 3-year bar on re-entry; overstays of one year or more trigger a 10-year bar. If you realize you will overstay, contact your visa sponsor or an immigration attorney when ready — in some cases, filing for an extension or change of status before your visa expires can prevent penalties.

Can I study part-time on an F-1 visa?

F-1 visas require full-time enrollment, which typically means at least 12 credit hours per semester for undergraduate students. Part-time study is not permitted unless you have written approval from your school's international student office due to medical, economic, or other documented hardship. Studying part-time without approval puts you out of status.

Do I need a new visa if my employer transfers me to a different office in the US?

Not necessarily. If you are on an H-1B or L-1 visa and your employer transfers you to a different location within the United States, you do not need a new visa as long as your work authorization remains valid. However, if you are transferring to a different employer, you will need a new petition filed on your behalf before you can begin work with the new company.
