This procedure takes approximately 3-4 months. The process cannot be expedited; however, you may stay in the U.S. to await the results. In a few weeks after you mail your application to change status, you can expect to receive a “Notice of Action” document (acknowledgment of receipt). With the receipt number, you can track your “case status” at: www.uscis.gov.
The status change to F-1 or J-1 must be approved prior to enrolling in classes. If your change of status has not been received in time to begin school on the date indicated on the I-20 or DS-2019, contact your admissions officer and have it deferred until the next semester.
You will submit all documents to USCIS:
If U.S. Sponsor:
Please submit a form I-134 Affidavit of Support verifying he/she is willing to support you and a copy of his/her last bank account statement on bank letterhead, or a letter from the sponsor verifying employment and salary.
If Personal Funds:
Submit evidence that shows you have access to funds in U.S. dollars. Submit copies of your last three bank account statements showing all deposits and withdrawals from your savings and checking accounts. Foreign amounts must be calculated by current exchange rates into U.S. dollars. It must be demonstrated that you have access to the entire amount of funds to cover the estimated cost for the academic year.
Submit a copy of the “award” letter.
