Hello @Expat4Cebu,
Thanks for reaching out! I'm sorry to hear you're running into some issues updating your account information just now. When moving from country to country, unfortunately there's not a way to change the nationality of your PayPal account. You would have to close the account and reopen it (using the same email address if you wish) under the new country. You would want to remove your bank first so you'll be able to add it to your new account without issue.
I hope this clears up any confusion, have a great day!
