Question regarding work permit and open work permit

[reshma123]

I am currently in US on H1b visa and planning to apply work permit for Canada ... I have few questions regarding work permit

1: How much time will it take for the process? (I have a job offer)

2: Can I apply open work permit for my spouse (I am a programmer analyst)? how much time will that take?

3: Can I again re- enter into US with that work permit visa?

Plzzzzz help me

Thanks in advance
