Temporary U.S. stays

Choose a category that matches your purpose.

B-1 / B-2

Business visits & tourism

B-1 generally covers permitted business visits such as meetings and negotiations. B-2 covers tourism and personal visits. Visitor status generally does not authorize U.S. employment or degree study.

F-1

Academic study

For qualifying academic or language programs at approved schools. Coordinate with your designated school official on enrollment, status requirements, and any authorized practical training.

M-1

Vocational study

For qualifying vocational or other nonacademic programs. Employment options are limited; eligible practical training generally follows completion of the program.

J-1

Exchange programs

For approved exchange programs, including certain research, study, teaching, and training activities. Requirements depend on the program and sponsor.

Employment

Investment

An option for qualifying treaty nationals investing in and directing a U.S. enterprise. Nationality, investment, and business requirements apply. Explore the E-2 visa →

For international students

Plan study and employment together.

OPT and STEM OPT

Eligible F-1 students may apply for up to 12 months of optional practical training related to their major. Pre-completion OPT can reduce the time available after graduation.

Certain eligible STEM graduates may apply for a 24-month extension, subject to additional degree, employer, training-plan, and reporting requirements. Training authorization, school recommendations, and filing deadlines need careful coordination.

Visa, entry & authorized stay

Understand what each document controls.

A visa allows you to seek admission; it does not guarantee entry or determine every aspect of your stay. Your admission record and status conditions govern your authorized presence and activities.

Before changing schools, employers, activities, or travel plans, review the effect on your status. An extension or change-of-status request does not automatically permit new employment.

Common questions

Answers before you begin.

Can I work while visiting on B-1/B-2?

Visitor status generally does not authorize employment. Permitted business visitor activities differ from performing productive work in the United States.

Can every F-1 student work off campus?

No. Employment must fit an authorized category and its conditions. Work with your school official and obtain any required authorization before starting.

Does every J-1 visitor have to return home for two years?

No. The requirement applies to certain exchange visitors. The program, funding, training, and applicable rules need to be reviewed.

Can I change status instead of leaving the United States?

Sometimes, depending on your current status, eligibility, timing, and the category sought. A change of status and obtaining a visa abroad are distinct processes.
