Wow! That’s quite expensive! I was thinking of printing and filling it out myself and have my fiancé fill out the page where his sign is needed then have it scanned then I’ll print it out. To answer your question, according to the USCIS site:
“The edition date is 4/25/2022. You can use the old form till June 27, 2022, but best to use the new form for those of you who are still waiting for the consulate interview.”
If your interview is before June 27, 2022, I think the old form should be okay. However of it’s after that date, I think you’ll have to use the updated one.
