Work Visas and Employment-Based Immigration: Common Questions

Answers on getting a work visa without a job offer, switching employers, the H-1B cap and lottery, F-1 student work and changing from a visitor visa.

This page answers common questions about working legally in the United States: sponsorship, changing employers, the H-1B lottery, student work and changing status from a visitor visa. It is for workers, students and employers weighing a work visa or employment-based green card path. The answers are general; each visa category has its own rules, and they change.

Can I get a work visa without a job offer?

Most employment-based visas (H-1B, L-1, etc.) require a U.S. employer sponsor. However, certain visas like the EB-1 for extraordinary ability or investor visas (E-2) may not.

Can I switch employers on a work visa?

It depends on your visa type. Some require new employer sponsorship and USCIS approval before switching.

What is the H-1B cap and lottery?

The H-1B visa has a numerical cap and uses a lottery system. Registrations are submitted in March for each fiscal year.

Can students on F-1 visas work?

Yes, but with restrictions. On-campus jobs are allowed. Off-campus employment like OPT or CPT must be authorized by your school and USCIS.

Can I change status from visitor visa to work visa?

In some cases, yes. This process requires careful legal analysis and approval by USCIS.

How Claudette helps with this

Claudette starts by asking about your education, work history, current status and any employer who may sponsor you, then shows which work visa or employment-based green card categories may fit. She builds a document plan for the category, prepares the forms from your answers, and checks your status dates so a change or extension is not filed too late. Because a work-visa filing often involves an employer, and some questions are close legal calls, attorney review is available as an optional add-on.
