If I knew that thread was going to implode like that, I wouldn't have been so chill about checking it... It ended being locked before I could check it again, I'm sorry I was away!
For the record I just wanted to say I haven't done anything illegal with my paperwork (to my emotional detriment at times!) and I'm not planning to.
Also I've been in artist alleys before, back in my country, and I've had another artist friend sell stuff of mine alongside theirs way in the past. They were chill. I've dipped my toes into joining american artist alleys before but I found it confusing so I thought I'd ask people about it in case there was more flexibility than I thought.
I'm sorry if I said something taboo or something, it comes from lack of knowledge, not desire to do LE CRIMES.
That said, thanks for the responses! I'll probably wait until my naturalization is finished since it might be at the end (maybe. It is paperwork hell after all).
That's what I have left to say on the matter. The thread is locked so I won't want to be rude by continuing the matter somewhere else either!
With that left behind, have a friend.
