As an applicant for a student visa to the United States, you are expected to prove that you can cover your tuition and living expenses. This means that you’ll need to cover not only for your own expenses, but those of your spouse and children, if any, and if they will be staying on with you in the United States. You’ll have to do this without relying on any employment that you might pick up in the United States while you’re a student—and without your spouse or children working at all.
If you will be on F-1 (academic student) status, your financial resources must clearly cover a 12-month academic term. And, you must show indications that your additional years of study will be covered as well. The U.S. government doesn’t expect you to be able to pay for all your years of education right away, but it does expect you to show where the money will come from.
Similarly, if you will be on M-1 (vocational student) status, your resources must cover your entire 12-month (or shorter) study term.
Your sources of financial support can include personal funds; personal assets or pieces of property that are readily convertible to cash; pay from work that you do as part of a fellowship or scholarship; or specified funds from other persons or organizations.
As part of the application process, you will need to gather documents that will supply evidence of the existence of these things. For example, you might show evidence of:
If your family members will be supporting you, they can use a USCIS Form I-134 to indicate that they not only have the income and assets you’ve shown, but they are willing to spend them on your studies and living expenses.
If individuals who are not members of your family are willing to support you, use any of the types of evidence mentioned above for family members, including a Form I-134 Affidavit of Support.
The person who decides whether to issue your visa will wonder, however, why someone who is not related to you will want to pay for you to get an expensive U.S. education. For that reason, non-family members should also write a sworn statement explaining why they are so willing, able, and motivated. The statement should mention that the person understands that he or she is not just a “backup” if other sources fail, but will be immediately responsible for paying all or part of your tuition, fees, and expenses.
