US Immigration from Philippines

My fiance made it to USA from the Philippines. We got her SS card then we got married. She would like to change her name. I understand we would have to go back to the social security office. How does this work when her main ID is her Philippines passport with her old name? If she wants to fly somewhere, she has to book in her old name? We want to get a bank account setup, is it easier before or after the name change? Basically, we don't know how the name change works.

Is there anything we will need to do differently on the AOS paperwork?

Thank you for your help

I have spent a good 2-3 hours trying to find these. I do see lists, but they either contradict each other or appear to be outdated. Can any kind soul out there enlighten us. We feel so close to the finish line and at the same time it feels very elusive

Hi there! please help me. I tried to pay for my daughter's green card fee today before she gets here. But it keeps showing this on the page " We could not find the A- Number " . The numbers I typed are from her visa stamped passport . Added 0 , didn't add zero but it's still not working. Should my daughter call them or just wait for when she gets here to pay? Thank you for your help.

Hypothetically, let's say our embassy interview is on a Friday -

Medical has to be completed 2(?) days prior to the interview, so would that be done Tuesday or Wednesday??

Biometrics have to be done how many days prior to interview??

Mahalo for your continued help.
