Can I use a US PlayStation Network card if I live in a different country?

I'm trying to buy some DLC for my games, but since I'm living outside the USA I can't use my credit card to add funds to my PSN wallet. My country was not listed when I created a PlayStation Network account, so now my only hope is a PlayStation Network Card.

I have created a separate US PSN account for purchases; can I use a US-based PlayStation Network Card to add funds to my PSN wallet? Has anyone tried this before?

UPDATE

I tried is and it's working. Bought a digital PSN card from they are really fast.

Thanks

I have done that myself.

Since i'm not from USA, i created a different account i buy credit for it to buy some stuff. The only restriction is that in order to play or use the stuff you buy with that account, is that both are as users in the same PS3 system.

This is necessary since it has to check for the user who bought it, but you can freely use the games/stuff for your main account

You can set up another Profile and configure it as a US account, that's what I've done so I can buy things off the US PSN store which are regionally restricted here in my country. Also so I can buy and redeem cheaper 4SaleUSA.com bought PSN codes
