I am a citizen or business of Canada, or another foreign country, and I don’t have a U.S. address. Can I still file a trademark in the United States and is there extra cost or additional paperwork required?

Yes. You can file a trademark in the United States as a foreign citizen or business as long as you are represented by a U.S. licensed attorney like us. You do not need a U.S. address to file a trademark in the United States and there is no extra cost or paperwork required.
