Changing Google Play country: Are there any side-effects when it comes to available apps? The question of how to change your Google Play country has been asked over and over. However, it's not clear whether this has any (unwanted) side-effects when it comes to apps, and especially those with region restrictions.
Some possible issues that come in mind:

What happens with any free country-specific apps you have installed in the country you currently use? Will they cease working? Will they cease receiving updates?
What happens with any paid country-specific apps you have installed in the country you currently use?
Is it possible for an app to have different country-specific versions in two countries? What happens then?
Can you change back your country any time you want, or is there a limit on how often you can change it?

This may seem like a dumb question, but I have heard some horror stories from friends who changed country in Apple App Store, only to find content they had purchased inaccessible. So I don't take the safety of this operation for granted.
I did this when I moved across countries - the apps are unaffected. If you had apps which are available in the earlier country then you can continue updating and using them. The only downside is that if you have credit in your account, then that doesn't appear in the new country. You can still use the credit if you change your play store country back to the old one.
