US Immigration from Barbados

I am new to the site, but I see a lot of comments about apply for expedited processing. How do you get qualified? I know I need to email the consulate once my file is DQ'd, but I am wondering who qualifies? And how long does it usually take?

For those who already have had their interviews, how long did it take for your case to go from active review to DQ with the NVC?

My minor son and I both moved to the US in 2016 via green card and live in NY. I applied for naturalization in July 2021 but can't figure out how to apply for naturalization for him to make sure he'll get his citizenship at the same time I do. Help.

Had my interview today everything good but I did admit to working with no ead and apparently my medical might be expired..is this grounds for denial????? Spouse is usc

So had NOA1 03/26, biometrics oct 8. Oct 11 requested EAD expedited, oct 13 EAD expedite under review then oct 19 interview scheduled for November 18. Has anyone experienced this before? Maybe am just anxious I guess just seems weird
