US Immigration from Nigeria

Hello VJ s, please your advice is needed. A friend of mine recently filed for CR-1 with his US citizen wife. He is a non-USC and he previously had a kid with his ex- girlfriend before they separated and his ex is a non-USC as well. During his application he didn t mention his kid to USCIS. Will that kid become a US citizen when his dad naturalise?

How long can my case be on ready for me to pick an interview date .the interview date am seeing r not decent for me to pick right now.

We are under review at the USCIS and we are trying to set things in motion so when we get approved, we don't wait too long to jump on to NVC part.

My Question:

1. Since we are planning to file jointly, does the Beneficiary have to be issued an ITIN before we can proceed with NVC (the affidavit of support part which involves Tax returns? Our approval estimate time is May, 2022 and we plan that my wife takes a trip down here in May, so she can visit and for me to sign the forms. Does it mean we have to wait till the joint filling is approved before we can present the Tax refund as "support affidavit" evidence? We are told it takes an average of 7-11 weeks to get an ITIN number. Why we aren't using the post to send from here to the States is because there have been issues of passport loss, damage etc.

Please, special contributions from individuals who have filed jointly for their spouse(s) from a third country, mostly Africa and the walk-through will be highly appreciated. Thanks

What should we put here if I am only sponsoring my spouse who is the immigrant and an elderly parent who does Not live with me but I file as a dependent on my federal tax return?
