Form I-134 – Affidavit of Support

Form I-134, Affidavit of Support is a legal document used to show the United States
government that a visa applicant is being sponsored by someone already in the United States.

This Affidavit of Support is filed by the U.S. resident who is supporting the visa
application of a foreign resident.

The purpose of this form is to show that the person coming to the U.S. will not become a public
charge and that the sponsor will act as a financial fallback.

Form I-134 is mostly used to support nonimmigrants visiting the United States. A different
Affidavit of Support (Form I-864) is used to support immigrants seeking permanent
residency in the U.S.

How do I file Form I-134, Affidavit of Support?

When a sponsor files Form I-134, they must also submit evidence that they have the financial
ability to support the sponsored foreign resident. They do that by attaching the following
documents to the affidavit:

• A statement from an officer of your bank with the date that your account was opened, how
  much was deposited into the account in the past year and the present balance.
• Statement from your employer on the company’s stationary with the date you were employed,
  the nature of your position at the company, how much you get paid and whether or not the job
  is temporary or permanent.
• If you are self-employed, include the copy of your last income tax return or report of
  commercial rating concern. Also, if applicable, a list of bonds that you hold with serial
  numbers and denominations.
