That could be problematic for receiving USCIS mail, even if you reported the address changes.
Do you have an online account, and if so what does it say when you log in?
Are you sure you’ve gotten the whole background story from your wife?
The pages and pages of redacted documents makes me think there is more to this than just an unfounded suspicion that she was already married at the K-1 interview.
This seems like a clerical error. An undeliverable notice of receipt shouldn’t result in a cancelled petition.
Do they have your correct current mailing address? This may be one of the times that a call to USCIS could be in order.
I would also notify them in writing that you want the petition to remain active.
I’d make 100% certain that it was a certified copy of the marriage certificate. Our “on the spot” marriage certificate was a commemorative one, similar to the souvenir “birth certificate” the hospital gives you when you have a baby.
Suitable for framing, but not a legal document. YMMV.
Different jurisdictions do things differently. You need to research how to go about that for your specific location.
I can't imagine a legal document such as a marriage certificate being given out on the spot.
This is an obvious drawback to waiting until the end of the 90 days to marry. It can take several weeks for the marriage to be recorded and for the certificates to be available.
A cursory glance/click shows exactly how to order one.
Most people try to come over prepared with such documents before immigrating.
But did you read the link Mike posted? USCIS has info on which types of documents are acceptable by country.
For the marriage certificates, you will need to figure out how to request those from your county/state once you are married. That info will be easily found on the website for your local county government.
Now I'm thinking perhaps you don't understand the meaning of certified copy?
It isn't a process of "certifying" a copy of something already in your possession. It is an official copy of the original document (owned by the county/city/state), certified by the county clerk or registrar, and usually has a raised seal. It is equivalent to an original.
You should have certified copies of all of these things, regardless. Why do you not have a certified copy of the marriage cert? You'll need several. Most vital records offices charge a couple of bucks per copy.
I don't think that is what Boiler meant. It is much more likely to take two years than one.
There is a long queue for the interview. There is a significant wait time even for CRBA appointments, from what I have heard.
