My husband his his first atp in CDJ next month and we are trying for a k3 visa, do we submitt the I601 waiver then at that apt? I'm assuming yes but I was just wanting to really make sure about it. Thanks.

You will not be allowed to submit the waiver at the first appointment:

When a consular officer makes a determination of inadmissibility at the time of the immigrant visa interview and a waiver application may be submitted under 8 CFR 212.7, the applicant will be given a USCIS waiver letter, which indicates that the applicant may go on-line via INFOPASS to make an appointment to come back to the Consulate in Cd. Juarez to submit an I-601 or I-212, as applicable, with a fully documented waiver packet.

* These INFOPASS appointments may be scheduled prior to the immigrant visa interview, but they must NOT be made for the day of the immigrant visa interview. For those with waiver packets fully documented and ready for adjudication, the earliest such a waiver review appointment should be made is a day after the immigrant visa interview. A better approach may be to wait at least two days to make sure that the fingerprints taken on the date of the immigrant visa interview have cleared.

* In order to set up this process, Mr. Janssen had to find staff to be able to do fingerprint intake on the date of the immigrant visa interview as well as to accept the G-325.

* When the waiver applicant comes back to the consulate with the COMPLETE and FULLY DOCUMENTED waiver application, a USCIS employee will review the packet (not interview the applicant), and if the case is a clean one and clearly approvable, the waiver application may be approved that day. Then, the Consulate will either approve the immigrant visa that day or within the next one to two days.

* If the submitted packet is not clearly approvable, then the application will go into the regular processing waiting line (10 TO 11 months) and the applicant will be instructed to provide additional supporting documentation to USCIS. Thus, using this process, the applicant will get a second chance for review versus exposure to a denial at the time of the first review.

I believe you have to set up a 2nd interview to turn in your waiver packet, you should set it up through infopass
