If you not staying in the U.S there is a 90% chance that you might experience this restrictions from paypal, most times issues like this happens they just want to confirm if your credentials are legit and if you not running any fraudulent transaction, and most times people experience this because of the different documents they use in registration. Infact I once experience something like this and I had some money in my PayPal account I want to withdraw and the next thing I saw was I will have to wait 180days to be able to do that I was so annoyed that I left the account luckily for me it was just a small token.
