USD withdrawals are available in two forms:
You can withdraw to a USD debit card
You can withdraw to a US Bank account if you have a Social Security Number (SSN)
A registered SSN, or Social Security Number, is a unique identification number issued by the U.S. government in order to identify US residents.
If you don't have an SSN or would not like to share it, the only withdrawal option is to withdraw directly to your debit card. The app gives you this option when you select the payment method.
