Hi @bdfesg4thty,
Welcome to the community, and thanks for your first post here!
While you can accept payments from internationally issued cards, the ability to charge your customers in different currencies with the Square app is not currently supported.
Payments made from internationally issued cards are processed in the currency associated with the country from which you created your account. Any currency exchange that takes place, will happen on your customers side at the exchange rate set by their bank, or card issuer.
