It depends on the queue at NVC for your consulate. Once you are DQ'd you get in line at NVC. When your case reaches the front of the line, NVC will schedule the interview.
The interview date is irrelevant to CR-1 vs IR-1 (if that is your strategy). If you enter the US after 2 years of marriage, then you will be eligible for a 10 year card. I'd say you are in good shape for a 10 year card.
Why would a foreign passport renewal be related to an expired Green card? I'm not connecting the two. You don't need a Green Card to renew a foreign passport.
Honestly, I have no idea what their protest is about. Lower taxes, secure borders, removing illegals thugs and criminals from the country, lower cost of living? These people are bunch of sore losers who are perpetual imaginary victims.
Nothing really happens at NVC for a K-1 case. They simply assign a case # (which you have), then forward the case to the consulate when requested by the consulate. What is the CEAC status of your case?
Not an issue. Just accurately report CURRENT annual income. CURRENT annual income is calculated as follows for an employee:
Gross income from latest pay period stub multiplied times the number of pay periods per year (12 months).
