I am a U.S citizen, and currently a nursing student. My mother and father are planning to immigrate to the U.S. Since I am a student, I am not able to sponsor them but they are willing to sponsor themselves by providing financial support documents/proofs like property ownership (two paid-off houses), cars, bank statements, and etc. Also, I am wondering if it is possible that they open an escrow account for themselves and deposit for instance $50k or $100k into the account as a financial support? Also, my father has had his own business for 20-30 years now and might be able to provide proof of ongoing income, as well. Any professional and legal advice is much appreciated!I guess my explanations are a little confusing. I will definitely fill out and sign the Affidavit of Support documents for my parents. I can take all the responsibilities except the financial matters because of my insufficient income. I can provide them with room and board too, if that matters. But my question is, can they sign the affidavit of support as co-sponsors? P.S. My mom came to visit me last year and stayed for 6 months. She had presented the aforementioned financial support documents to sponsor herself, if that makes any difference. Thank you all for your inputs.
