Canadian Permanent Residents Vs H1B Holders

I found this in a mail from an immigration consultant. I am not sure how much this is true but it really is a good starting point!

Canadian Permanent Residents Vs H1B Holders
-------------------------------------------
While we apprise you of some of the interesting facts about Canada, we are excited to present you a crystal clear comparative analysis between a H1B Visa Holder in USA and a Canadian Permanent Resident based on the feedback received from many of our clients who currently hold an H1B status.

1.H1B visa holders can not change sponsoring employer whereas Canadian Permanent Residents are free to move between jobs and locations, work on contract as a consultant, which could result in tax benefits.

2.H1B visa holders are unable to start own business whereas Canadian Permanent Residents can commence their own businesses.

3.Many H1B visa holders face the risk of going back to their home country if their Green Cards are not applied before the 6-year limit or when H1B expires, such is not the case with Canadian Permanent Residents. No such risk exists. At the very outset, new immigrants receive a permanent residence visa (very similar to the USA Green Card).

4.H1B visa holders cannot sponsor dependents other than spouse/children, whereas, once you are a permanent resident, you can sponsor other family members also who are dependent on you (brothers, sisters, parents etc.)

5.If a spouse of H1B visa holders wishes to work, he/she has to arrange for sponsorship from potential employers; thus creating a barrier to finding employment, whereas in case of Permanent Residents, spouse can legally work in Canada, as he/she also has the Permanent
Resident status - no permits or authorizations needed.

6.Citizenship - is a LONG wait. First the green card and then many more years to citizenship. Whereas, in Canada 3 years of residence entitles you to apply for citizenship. Canadian Citizens does not need H1B to work in USA.

Pursuant to new IRPA a permanent resident only has to stay 2 years in 5 years period to maintain his/her permanent resident status.
