OS X/iOS: Are purchased apps still available after changing regions?

Question

Apple App Store

When moving, it is logical to change the region in iTunes, AppStore. All previous purchases were made in our native store. Will they be available on change?

Answer 1

If you move to a new country, you can change the country of your existing iTunes Store account (Apple ID) on your iPhone, iPad, iPod touch or Mac or PC. If you don't change your country when you move, it's possible that your credit card won't be accepted for payment. For example, only German credit cards can be used to buy content from the German iTunes and App stores.
