Advisory Opinions
Q. What is an advisory opinion for a waiver recommendation case?
A. An advisory opinion is a request for a statement from the Waiver Review Division as to whether an exchange visitor is subject to Section 212(e) of the Immigration and Nationality Act, as amended.
Q. When should I request an advisory opinion?
A. You should only request an advisory opinion after you have participated in a J-1 program and you have doubts whether you are or are not subject to Section 212(e).
Q. Can anyone request an advisory opinion on my behalf?
A. Yes. Your attorney or your responsible/alternate officer may request an advisory opinion for you.
Q. What information should I include in my request for an advisory opinion?
A. You should mail legible copies of all your DS-2019/IAP-66 forms along with the written request for an advisory opinion. We do not recommend sending your request by fax because DS-2019/IAP-66 forms frequently become illegible during the fax process.
Q. Where do I send the request?
A. You should send your request to the following address:
U.S. Department of State
CA/VO/L/W, Visa Services
2401 E Street, NW, (SA-1)
Washington, DC 20522-0106
The request for an advisory opinion should be made by letter and must provide legible copies of all of the exchange visitor's DS-2019/IAP-66 forms for the entire time he/she was in J status. You should provide a self-addressed, stamped envelope for where you would like the advisory opinion sent.
