### Step 7 - Fill in the country and currency

* Set the country to **Brazil**
* Select **US dollar (USD)** as the currency. This is required because Meta uses the dollar as the base currency, but it converts to Brazilian reais on your card's invoice afterward
* Then click **Next**

### Step 8 - Fill in the card details

  - The amount charged will be based on the dollar exchange rate on the day the invoice closes
