US Immigration from Morocco

please help, we did ds-160 but dont know what website to use to pay for the interview and choose a date

My fianc had his interview today but was denied the visa. Agent claimed the approved I-797 form expired in July. However, the embassy did not have any available appointments until August. I am unsure if there is anything more I can do

Hey, all. My fianc and I received our NOA2 mid-June. It's taking 60-90 days for shipping to DOS/NVC. My fianc (beneficiary) was living in Turkey, so we had Ankara as embassy for interview. My fianc has since moved back to his home country of Morocco, and we need to update the location to the consulate in Casablanca. I keep looking online (USCIS website, groups I'm in, etc.) but am unsure of when or where is the most appropriate time/entity to notify of this change. I did a PI and of course as NVC has not received it yet, they said they cannot locate the case and will "work with USCIS" (it's been two weeks and heard nothing back). Is anyone able to assist with how to go about changing this to minimize delay? We really don't want it going to the Ankara embassy and then taking longer to transfer. Thanks in advance.

It states on the NVC website: "If a visa is not available because of statutory limits on the number of visas, NVC cannot schedule your interview." Does anyone know the number of visas granted to each country by the U.S.? Or a website that might have that information?

Coming from RAK to EWR, with a K1 visa, does anyone know if a transit visa is needed, i.e. from Marrakech to Newark, with layover in CDG, LIS or YYZ
