Buying my first house

[Hideaki Yen]

Hello! I'm currently attending university outside the U.S. and am panning to buy my first home when I get back. However, I don't have a credit card, and thus no credit score. Will this effect my chances of getting an FHA loan as a first time home buyer? There are so many conflicting answers online; some say I need some and some say I don't need any at all for your first home.

Thank you!
