change country app store temporarily
I want to change country app store to download two apps and return?
You can't use a country's store unless you are in that country and have a billing address in that country. If you are in that country you can change the country on your account and put your billing address and payment details for that country on your account : Change your Apple ID country or region - Apple Support
If you aren't in that country, and if the apps aren't in your own country's app store, try contacting their developer and ask them to put them there
