I sent a message to Smashwords to request a letter indicating my intention to self-publish. i already received a confirmatory email indicating this letter will be sent to me in the mail.
I headed down to my local passport Canada office yesterday, in order to apply for a certified copy of my passport, which will need to be sent to the IRS, along with the above letter, for the ITIN application.
For $45, I can get up to 3 copies. I did choose to ask for three, just in case something is incorrect with my application when I finally send it in. It will take two weeks to get the certified copies, and I am unsure how long it will take to get the letter from Smashwords. But I am finally on my way to getting my ITIN! Step #3 will be the last one – filling out the W-7 and sending everything to the IRS. I will update again at this point.
