Can I change my PayPal address to another country or region?
No. The laws applicable to PayPal accounts differ by country or region, so you can only register local addresses in Hong Kong in your PayPal account. If you're moving abroad, you’ll need to close your existing account and open a new account.
If you maintain residences both in Hong Kong and the other country or region you move to, you can have 2 PayPal accounts as long as only one is a Business account.
