US Immigration from Thailand

My fiance scheduled her visa interview in Bangkok. She rescheduled the interview once when an earlier time slot was made available. Now an even earlier time is available and we are interested in rescheduling again. On the reschedule page it says "If you cancel this appointment, then you will have exceeded the limit of appointments canceled, and will not be able to schedule another appointment until another MRV fee has been paid."

What is unclear to me is whether they mean that if we reschedule again after this time we'll have exceeded the limit of appointments canceled or if they mean if we try to reschedule this time that we'll have exceeded the limit and need to pay again. Anyone know definitively from experience? Thanks.

Hello,

How long after you pay the visa application fee (DS160) do you get the email saying you can now schedule the interview?

Can you pay the visa fee online after submitting the DS-160?

Hello,

Me and the wife are looking at going to Thailand from August until November. Her green card expires January 2022. Is there any issue with being out of the country for 4 months right before the removal of conditions on her 2 year green card? Anything to watch for or keep in mind?

Hello, I filed I-751 since January 12, 2021. Received my NOA on Feb 27 but still hasn't received Biometric Appointment Notice and it's been over 3 months now. Does this happen to anyone? I'm trying to contact them by the phone, sent e-request but has no luck. They never response. Any suggestion is much much appreciated here. Thank you!
