US Student Visa Overview
The United States welcomes foreign students to American language schools, high schools, universities, and other institutions of higher education. Many learning institutions are approved by the USCIS to accept foreign students as full time students. Once accepted, an owner of the F-1 Student Visa can also change schools and universities without leaving the country.
Eligibility requirements
Anyone aspiring for a US student visa must come to the United States to pursue an academic program in an institution recognized by the government. One must have a valid education purpose for coming to the US and be a full-time student. The student can stay in the US as long as he or she is enrolled in school. Meanwhile, being a part-time student on an F-1 visa is not possible.
Traveling on F-1 Student Visa
It is possible for foreign students with a valid F-1 Student Visa to enter the United States multiple times, as well as being allowed to travel within the US. In doing so, one should have all the necessary documents and signed authorizations to avoid any problems. The passport must also be valid for a certain amount of time.
Working on F-1 Student Visa
Students with a valid F-1 Visa may work on campus as long as they are enrolled in the school. They may also apply for Curricular Practical Training to gain work experience in their field of study while being a full-time student; or may even take advantage of the Optional Practical Training once the degree is completed. Also, they can be sponsored by a prospective employer for an H-1B Work Visa.
