Thank you all for the advice. Because of some unrelated family complications, my parents won't be able to file until early June. Ideally, I'd like to submit all the necessary documents as soon as possible rather than waiting 1 month or so until the taxes are filed. This is why I'm debating if submitting I140's for 2022-2023 for my parents and the W2's for 2024 would be sufficient so then we don't have to wait. Would submitting now with the W2's of 2024, and then submitting the 2024 I140 as soon as the taxes are filed be the best approach? or is that a bit of a risk?
Thanks again!
