Q: When changing an apple id to another country do all your previously bought apps stay available?

Hello there, Kristrel.Gabriela.

It sounds like you are changing the country store for your Apple ID and want to know about the availability of your previously purchased content. The following Knowledge Base article offers up some great information that answers those questions:

Change your iTunes Store country or region

In particular:

What you need know before you change your country or region

When you change your iTunes Store country:

• You need to update your billing address to one in your new country. When you change your billing address, the primary address in your account at My Apple ID and your other Apple services, such as the App Store and iCloud, automatically updates.
• You might need to update your payment method. For example, only German credit cards can be used to buy content from the German iTunes Store and App Store.
• You won't see the items that you purchased from the previous country’s store in your Purchased section.
• You won’t see the items from your iCloud Music Library that you matched, uploaded, or added from the previous country’s store.

When you make a purchase in the iTunes Store, App Store, iBooks Store, or Mac App Store, the country in your iTunes Store account information must match the country listed in your account at My Apple ID.

Thanks for reaching out to Apple Support Communities.

Kind Regards.
