AP and re-entry US.Plz help!

[Mila]

I am working in US with H1-status.I got my canadian immigrant visa and I have to land in Canada in May 2001, and I want immediately to return back to US .My I-797 will expire in August 2001.I applied for I-485 and I got my Advance Parole.Does anybody know,what documents I need to come back from Canada to US?Should I apply for new H1 visa for re-enter to US or I can just show my I-797? Should I show my AP for re-enter to US?When I will enter US from Canada, can be any problems?
Thank you!

Mila.

I am in a similar situation. I got my canadian PR and planning to make an entry in May. I have my EAD and AP. I want to know if I will have any problems in getting back to US on my AP.
