Can I change my billing address? I filled in the information according to my W2 form. I need my billing address to be the same at mailing. Where will my paycheck come?

I wrote my mailing address, which is in my home country, however at the end of the procedure it asked for the billing address and I couldn't choose my home country, so I wrote a US address, but I will not be able to take my paycheck from there. 
I need it to come to my home country, in case of problems with bank transfer
