I came to the United States on F1 (Student Visa) in 2015 and I graduated from school then I got OPT (Optional Practical Training) and I got Employment Authorization Card and I am working legally right now. On the other hand, my Dad is a permanent resident (Green Card Holder) and he applied an I-130 (Petition for Alien Relative) for me in 2011 and the application is with the NVC (National Visa Center) right now. My Priority Date now follow the table for filing visa applications Not the final action dates table in the Visa Bulletin so I can apply. I have 2 options now: 1) Adjustment of Status 2) Consular Processing
Since I am physically present in the United States I want to apply for Adjustment of Status. My Dad is the Petitioner and I am the Principal Applicant. My question is for my interview for Adjustment of Status: Should my dad come to the interview with me? or is it optional? On the other hand, my Dad had been in my country (Out of the United States) for more than 6 years, I know that he has not to leave the United States for more than 6 months but he had some health condition and he had to go to a hospital in my country, but he came recently to United states for a month and he got his SSN and he got his ID and he has a bank account and he filed for Taxes for the last 3 years but he didn't work in the United States at all. My Dad got his Green Card in 2011, but his SSC in 2018. I know that we need a joint sponsor for income requirement and my brother can do that. What are the documents that are required from my Dad for Affidavit of Support?
The thing that I am concerned about is domicile requirements for my dad. My Dad came to the United States for a month but he had to go back to my country (Outside United States) for medical reasons and he can come back again for the interview. My question is what are the documents that are required from my dad to Proof of his residency/domicile? If there is any suggestion that would help please advice me?
