Paypal is country specific so if you move countries you have to open another paypal account in the country you reside in and add an address / phone number / bank accounts / cards from within that country.
You should really withdraw any funds / resolve issues / remove cards and bank accounts / cancel any subscriptions and close the old Paypal account before you move countries. If you don't then you may have problems doing so once you have moved and may need to contact customer services for help to resolve things.
If you go to the 'Help & Contact' icon on the PayPal website. Then if you click the 'Contact Us' link at the bottom of the page. From here, if you click the 'Password and Account Access' option, then 'Login Problems'. On the next page, you will see a 'Call Us' option. You do not need to be logged in to use this feature.
