H1B for Canadian

[kachin]

I am a Canadian citizen. I was granted my first H1B for October 2009.

1) When is the earliest date that I can cross the border? I read somewhere 10 days.

2) How exactly do I cross the border since visa interview is not required for Canadians.
- do I need a passport photo?
- do I need to pay $131 at Scotia Bank?
- do I need to fill out DS-160?

3) I'm thinking of taking one way Uhaul truck for the move. What forms do I need for customs and border?

4) My personal car is bought in US. I imported to Canada when I moved here. I need to take it to US again. How do I do that? forms?

If you can explain in detail, that would be wonderful.
Thank you for the help.

Yes, ten days, it's in the CFR.

2) How exactly do I cross the border since visa interview is not required for Canadians.

You need your passport or NEXUS card and the approved I-129 and/or I-797.

3) I'm thinking of taking one way Uhaul truck for the move. What forms do I need for customs and border?

Comprehensive packing list. Technically you should have owned everything for at least a year but they seem fairly laid back about enforcing that.

4) My personal car is bought in US. I imported to Canada when I moved here. I need to take it to US again. How do I do that? forms?
