Hi everyone, I have a doubt regarding i20 request. I got admit this Month from UCLA Anderson School

Hi everyone, I have a doubt regarding i20 request. I got admit this Month from UCLA Anderson School for MFE for fall 2018. Recently University has sent me a mail how to request i20. Can I show combination of education loan and parents funds as funding source? Will it become an issue for releasing i20, if I show education loan as funding source. Can I show that my parents are funding completely for education now and take a loan before Visa date and tell the interviewer that i have a loan? The i20 amount is huge and that is what confusing me. Thanks
