This question already has an answer here:
I will be doing a short term student visa on my American passport and I have a small problem. My father has a savings bank account. He stores all the money required for my education inside it.The last time he did an activity in this bank account was like more than a year ago. He has 18,000 USD in this bank account but recently he placed 3,000 USD . So are the 3,000USD considered ‘ funds parking ‘ They are not from his income. He is unemployed but has lots of properties so he sold a land and deposited the money . I also have a question , how recent should the bank statement be?
