This is _exactly_ what I did. Experience was great. SUPER easy. Took me about 2 months. Cost $300, filled out one form online, and sent a copy of my USA 2020 tax returns showing my income. Super, super easy.

If you're even KIND OF thinking about going I'd just apply today. You have nothing to lose and don't have to go if you don't want to. It gives a lot of flexibility.

Thanks. This might be a silly question but did you redact your social security number from the tax return you submitted? Also do you have a link to the official site you used?
