I am PH.D student, RA and will graduate next August. I will have my second baby next June and want to invite my mom to come over in the name of attending graduation ceremony. The problem is my first child is already F-2 and I only have 5000 dollars in my account. My hu*****and is H-1 and he has a different bank account with more money. Should I provide two bank statements for my mom's visa? Thanks a lot.
