Yes, my parents sponsor me and it's pretty much enough.  To be honest, I find a lot of opportunities here in U.S. while a lot U.S. peers are whining about contracting job markets.  And thank you sincerely for your encouragement.  

What I'm pretty sad here isn't that I lose some available credit limit. It is that I can't have an Amex Blue Cash Prefered card. Though there are other options, none are as good.
