I will change my status (J1 to F1) and the school is helping me. My J1 visa expires on dec 22. But I have a doubt about who can sponsor me. I have 3 options and would like to know which one is better: 1-My uncle has a greencard and can prove that he earn more than $1400 per month. 2-His friend is american and also can rpove enogh money to keep me. 3-I have around some money in my account in Brazil and also can show the alimony that my dad give to me, and the guy said that I also can show the money that I receive as an aupair. He also said that it is for apply for 1 month of study and after just extend that; because he said that for 1 month I just need to prove that I have $1400 ( the school is a English school and costs $450 per month).
I`m kind of afraid about how hard can be to take the F1 visa
