I am a Canadian citizen who has studied in the U.S. with a J-1 visa since 5 years ago, which means that I have now become a resident alien. I am still studying (for an advanced degree) in the U.S. For the past 5 years as a nonresident alien, I have been using the Canada-US tax exempt treaty Article XV.
I have researched that some countries limit the number of years you can use the treaty, but I could not find anything for the Canada-US treaty, nor can I find what the treaty says about being a resident alien in the US.
So if I still qualify to use the treaty, should I just fill out a Form 8833 to get the exemption? Are there any other forms to fill out?
If I can get the exemption, Article XV states "such remuneration does not exceed ten thousand dollars ($10,000) in the currency of that other State", does that mean I can only get exempted up to $10k? So for example, if I earn $12k, I can only get $10k of exemption, leaving the $2k to be taxed in the U.S.?
