US Immigration from Colombia

My gal is Colombian and we ve been together nearly continually for 2 1/2 years. Traveled during pandemic. She s studied here as a university student (left and returned and currently here. We met before she ever came here. Finishes this summer). We are planning on getting married but she and I are both unsure how much time we want to be in the US. Bottom line just want to be together. She has a tourist visa interview (sorry. The actual visa numbers confuse me) in Colombia in August. She also is in the last throes of getting her Portuguese passport from having a Sephardic Jew in her family.
The problem that confuses me (we ve spoken to two lawyers) is that her parents are getting older and she wants to visit them every six months or so. If she gets the tourist visa, can we file for green card in Colombia and can she come here for 90 day intervals and be with me if she doesn t work? What s the difference with a Portuguese passport. What are the limits? Can she come and go with either? We are trying to plan our lives past 90 days for first time in 2 plus years. Thanks!

I live part time in Colombia, with my wife. My brother is a permanent resident, of the USA for the last 57 years. Last month he came to visit us in Colombia. He told me he has a return ticket for the USA. (He has the onset of Alzheimer's) I then ask him, if he has his green card, he told me no, I then ask him how he expects to get back to the USA. I called his friend, and ask him to look for my Brothers green card in his apartment, he send me a copy, the green card has been expired the last 15 years. Can I file ESTA for him, he is a German citizen, with valid German Passport. Or what are his options to get him back to the USA. Thanks.

US consular refused my husband's CR1 Visa for specific reasons in 2022 now corrected and submitted. His CEAC case most recently updated with a message that read Your case was last updated *****. Do this mean they're considering the required documents?

We are NYC based and given the directions of where to file our I485, we were directed to file with the Chicago USCIS. I did not realize that there was also a NYC USCIS office until reviewing the processing times just today and now I am confused why we were asked to send our AOS to Chicago when we are in NYC. Either way, how can we know if our case is with the Chicago or NYC office?

My wife and I was not aware we could file for a SSN prior to her AOS and in New York State where we are located, it does not appear we have enough local documents to meet their proof to obtain an ID. Is it sufficient to have her foreign ID, a digital copy of her AOS NOA1 and a digital copy of her passport in case a police officer or ICE asks for identification?
