US Immigration from Barbados

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

My grandma left the US in 2018. She already had permanent residence filed by my USC mom. My grandma was ill and couldn't travel, then the pandemic hit. 88 years old and alone through this whole thing. We did not get a re entry permit but my aunt has gone to get her. We have a doctors note notarized saying she couldn't travel. Will she be let back into the US?

TIA

Considering everything going on how long is it taking to receive biometric appointment?? Filed in feb 2021. Is it with all service centers? Mine is Dallas
