The option to receive Paypal payments is sadly not available in Mongolia. You can only send payments for purchases funded by your (confirmed) credit card. So your account would be verified when you add and confirm that credit visa card.
Paypal varies a lot country to country and can only offer the services that the banks / governments of that country allow it to offer. There are quite a few countries unable to receive Paypal payments.
