My I140 already approved, waiting for the priority date of I1485(current April 2005, mine August 2006). Immigration to Canada was approved, medical exam need to be done. Worried if I land in Canada, can I get back to US? I know it is better not to travel to China after I140 is approved.

Thanks a lot!
