Credit cards are generally international. Are you using a debit or a credit card? What about paypal? Do you have paypal? Paypal can be transfered over several countries. Just link the card to paypal and then send money through there.
Sim eu tenho conta no PayPal eu gerei um boleto e paguei em reais estou esperando o saldo PayPal cair para transformar em 12 usd se for possível aí farei a doação.@danilo153315 if you want to know if it is or not. Try searching on the right buttom of the card, it shall say if it can be used internationally/online. And for the PayPal error. Ask your mom if she has a PayPal account herself. Since it might be added to a different one so it can be the issue.
