Student VISA:
To apply for a visa, take your passport and Certificate of Eligibility (Form I-20 or DS-2019, usually issued by UC Davis Services for International Students and Scholars after you are admitted by Graduate Studies), plus proof of adequate financial resources for your studies and living expenses to a U.S. Consulate or Embassy. The types of visas available to you are the F-1 student visa and the J-1 Exchange Visitor visa.
The F-1 student visa is ordinarily given to individuals qualified to pursue a full course of study at an academic institution that is authorized to admit international students. The J-1 visa is sometimes given to students who are supported substantially by funding from any source other than personal or family funds, for example, the U.S. Government, the students home government or an international organization. UC Davis Services for International Student and Scholars (SISS) can advise you on the appropriate visa for you.
Graduate students in F-1 or J-1 status must carry a minimum of 12 units or the equivalent of a full course of study as certified by the Dean of Graduate Studies. Non-immigrant students are not permitted to work outside the University without work authorization from the U.S. Citizenship and Immigration Services. They are only allowed to work within the University on a part-time basis.
Before a U.S. Consul will grant a visa, you must prove that you will have sufficient financial resources to meet all your expenses while studying in the United States. You must show documented evidence of the source of your funds and guarantee that you will receive them while at UC Davis. Unless you show written evidence of having resources for your entire degree program, you will not be granted a student visa.
