Question by Pablo T: Can I use stamps from outside of the US to mail letters within the US?
I bought postcards in Spain and I put Spain stamps (0.78 euros) on them but forgot to mail them there. If I want to mail them from my address (inside the US) to another address within the US do I need to put a US stamp on or will the Spain one work?

You’ll need US stamps to mail them in the US.
you can use them,
but it will be returned
.
Why don’t you just go to the post office and try to buy some American stamps with your Euros? Because that will work as well as mailing with European stamps.
