US Immigration from Dominican Republic

My fiancee and I are at the final step prior to scheduling interview. We completed the DS-160 and registered on the https://ais.usvisa-info.com/en-us/countries_list/niv webpage. We can not figure out how to pay for the Santo Domingo, DR page for the K-1 Visa and when we try to schedule interview says "system busy try again later". It has been 2 weeks getting same error. Please help.

I filed my I-751 back in December 2022 and the last update was last December where they transferred it to another office (NBC) as per USCIS page I could ask for an update since it's been so long, now my question is have you requested information and had a positive result? If so, how long after the request?

Thanks for any input.

My partner came here on a Fiance Visa. We married in the 90-day window and filed for Adjustment of Status. That is in process now. At some point, we anticipate we'll be asked to go for interviews. We are a same-sex couple and, under this current "administration," we are worried we will be subjected to extra scrutiny. Has anyone done an Adjustment of Status interview recently? What sort of evidence do we need to be prepared to provide? We've tried to follow the rules, but right now, that may not be sufficient. Do we need to be prepared to bring photos, videos, documents? Any advice is appreciated.

I started the AOS for my mother in May (I130) and I485 in July. She had her biometrics appt back in August. (no fingerprint, just the picture), this morning changed to CASE IS BEING ACTIVELY REVIEW BY USCIS, we are in Texas. How long approx will take from now and what is the next step

Thanks

Apologies if this has been asked before. I searched but did not see anything. If someone came to the USA on a Fiance visa, married within the 90-day window, and submitted the proper Adjustment of Status paperwork (in other words, they followed the correct process) ... but while that Adjustment for a Green Card was in-process, they filed for divorce, what would be the outcome? Clearly, they would no longer have their original sponsor and that original adjustment process would be stopped. But assume they then married a different person and then filed a new Adjustment of Status with that second marriage ... would that be allowed? Or would immigration flag this as some sort of fraud. I cannot find an answer to this question. I appreciate any insights.
