Change of region with $0,05 to spend

Hi Flash767,

Welcome to the Apple Support Communities!

You are correct in that your store credit does need to be less than the cost of a single item on the iTunes Store to add a different form of payment and change the country for your account. Please reference the following article for further information.

I can't change the country of my iTunes Store, App Store, iBooks Store, or Mac App Store account

If you have a store credit balance

You must spend your balance before you can change stores:

• If your store credit is less than the cost of a single item on the iTunes Store, App Store, iBooks Store, or Mac App Store, you can add a credit card to your account. When you buy an item, you will use the remaining store credit and charge the remainder of the purchase to your credit card.
• If you don't have a credit card, contact iTunes Store support.

If you are continuing to have issues changing your information, I would suggest following the link in the above article and contact iTunes Store support.

Have a great day,

Joe
