回复：To PJiang老师: Apply for AP & EAD after landing in Canada

... if I come to Canada from US next time, I must have an H-1B visa to re-enter the US from Canada and I can't use Automatic Revalidation any more.
- not true

Then he said that you must make a decision to cancel one. You can't have two to enjoy both benefits.
- you may make a decision after GC's been approved

1. Do I need to cancel my permanent resident of Canada, while I'm applying for permanent resident of US (with pending I-485)?
- no

2. I want to apply for AP & EAD. Will his remarks lead to rejection for my application of AP & EAD?
- no

How long does it take to get AP & EAD now?

Will it be better that I apply for AP & EAD several months later, not right after I became a permanent resident of Canada?
- no difference
