Unfortunately, even after months of waiting, it is possible for the USCIS to cancel an interview for a green card.
What do you do in this case? Why will the USCIS cancel an interview in the first place, and how can you take this information with you into the future?
Reading over the letter of cancellation
The U.S. Citizenship and Immigration Services discusses reasons for the cancellation of a green card interview. First, note that this is actually not an uncommon occurrence, and that in most cases, the cancellation of an interview has nothing to do with the applicant. Scheduling conflicts or administrative issues often top the list when it comes to reasons for cancellations.
So what do you do? First, read the letter of cancellation carefully. The USCIS will first send out the cancellation notice via online message. Then, they mail the physical letter. This will usually contain more information about the cancellation, and it may require a response from you. Be sure to read it carefully and do what it may request of you.
Keeping an eye out for your next move
Next, keep watch for any updates. In some cases, the USCIS will do all of the rescheduling for you. Staying informed and knowing what to expect next will allow you to get right back in once they get a new appointment set up. If you must deal with reaching out to them or scheduling another appointment yourself, this also allows you to get it done quickly.
Though green card interview cancellations are often a nuisance, it is certainly not an enormous hurdle on your path to getting your green card, especially if you know what to expect.
