The couple moved from Canada to US middle of 2019, husband now is holding H1b visa. Wife and one dependent child is holding H4 visa. Wife lives in US but work for a Canadia company remotely and has been filing tax return with Canada.

They want file 2020 tax return (MFJ),  Can I complete the 1040 return print and give to them ( attach to their W7 form)?

They will make a in person appointment for applyinh ITIN.

Thanks!
