Previous thread here for more context.
So my brother's son (US citizen by birth) is currently residing in Brazil and since turning 21 recently, he petitioned for my brother, also in Brazil so both can immigrate again to the US. The case was submitted through the NVC with a mistake being made on the I-130 at the beginning where the son entered my (uncle living in the US) address as his current residence. We were advised here in the thread above to correct the address on the next step/application.
Everything was submitted to NVC but some items returned. The most notable and worrisome is this one:
PETITIONER might not have a principal residence or be domiciled in the United States. Please submit proof of domicile. For more information on domicile requirements, visit https://nvc.state.gov/fin.
As noted above, he is currently in Brazil so technically, not domiciled in the US as he left at a very early age.
What should be done here to prove domicile? Apologies if this question is very obvious.
Also, there were about 5 messages sent through the portal asking to correct a few things but when viewing the documents section of the portal, only two files show a DECLINED. Should we do everything being asked through the messages or only submit the files that show DECLINED?
