US Immigration from Saudi Arabia

My wife is now a green card holder and will become a citizen in approximately January 2025 (3 years after obtaining her conditional green card).

She also wants to bring her parents and (currently) under-18 siblings to the US on an immigrant visa.

I just learned that her siblings can't come to the US with her parents as an immediate relative.

If her parents immigrate first and then sponsor their children (my wife's siblings on a preference relative 2), can this be done if the child is over 18, or does it have to be under 18? And do they look at the child's age at the time of application or when they arrive for the interview? We're worried the sister may be turning 18 right around that time.

Thanks!

Hi

in my upcoming interview for my ir1 visa in checklist I should bring all my kids original birth ( they are USA residents ) unfortunately I don t have it right now i have only certificate translations with copy for the original in addition their USA passport is that consider enough for me

There's a bit of a discrepancy in the certificates from Bahrain and Saudi Arabia. We've already uploaded the Saudi certificate, which expires on July 8th, but of course we won't submit it along with the other civil documents until we receive the Bahraini one, which has been massively delayed. Would the Saudi certificate be considered expired if we wait until after the 8th to submit it? I ask because my understanding is that the immigration process considers these certificates valid for a year, but I don't know if that still remains true when needing to actually submit it to the NVC. I appreciate any quick insight on this matter.

On the main interview prep page on State.gov, says to bring all the civil documents uploaded to CEAC and that you do not need to bring the affidavit or support or financial evidence:

However on embassy websites, it says you must bring the birth certificates of all your children even ones who won t accompany you (even though it s not required on CEAC) and says for family-sponsored visa you must bring the affidavit of support and IRS transcript etc.

So which of these is correct?

Doesn t anyone know if the medical exam can be done at a medical facility in a different country? Some I know are applying for immigrant visas in eastern Saudi Arabia but the medical office there that does US immigration medical exams is closing and the closest ones would be in Riyadh (4-5 hours driving) or in Bahrain, which is a lot closer. Bahrain has a medical office that does the US medical exam, but would the US consulate in Dhahran accept the exam from the office in Bahrain? And I m wondering if this applies to any other third country as well if anyone has any experience. And could someone do the exam in the US if they were in the US before returning to the country where the embassy will be conducting the interview?
