I have noticed that Visapro.com online forms seem to be superior "fillable" .pdf forms as opposed to those offered by USCIS or other sources. When I attempt to use the USCIS forms I often get inferior results or error messages. Has anyone else noticed this as well.

PS: Is it best to print out the forms front-to-back so that page 2 is inverted to page 1 ("flip-up" style as opposed to "flip-over") or does it make a difference? I'm thinking that the forms are given a two-hole punch at the top and inserted in a folder??

I haven't noticed this, but I haven't used Visapro. The pages should be one-sided.

I would stick with the 'official' ones from the USCIS and use single-sided.

thats interesting you say to use single sided....i got all my forms directly from the immigration office in atlanta and all of them were front and back. i dont think they would hand out two sided forms if they didnt want them would they?

Always print and use the forms from www.uscis.gov for your final version you send in. They are the only forms that are garunteed to be correct and up to date.

Visa Pro forms are superior .pdf fillable IMO and often they are more "up-to-date" than the government site IMO.
The government site had "problems" with their NEW I-129F form (for example).

Check your version numbers/dates. If the visapro form version is current, I'd go ahead and use it. Find out what the current version is on uscis.gov first.

And I always printed my forms on both sides of the sheet.
