US Immigration from Dominican Republic

We finally received our NOA2 today. I know I have to fill out I-134, but after that is completed, do I send that to my fiance to bring with him to his interview?

I m summiting my i130 what kinda evidence should I summit before they ask for anything.

Does anyone knows how to get through USCIS to get a representative ???

I'm going around in cycles.

We had our AOS interview today. The IO was very friendly and it was overall a good experience however he couldn't give the approval because they lost my husband's overseas medical exam at the POE. We did not know this until the IO started to search in our file for the medical. He did issue request for evidence for the medical and i693 form. How long after sending in evidence after an interview should we get an update? He did say he was going to recommend for approval but they just needed the medical to go through with it.

Anyone here applying for AOS whose case is being processed at the Mount Laurel servicing center in New Jersey?

Looking for updates on timelines once AOS case was received / sent.
