USA Work Visa...G/F and Kids?

Ok, if I am sponsored by a USA company, fit the bill, get an H1-B visa. What about my common-law wife and her two kids aged 17 and 18? Can they also travel with me? Work?

They would be in H-4. Go to school but not work. The US doesn't recognise common-law relationships for immigration purposes.

If you didn't get your application in by today then it's not likely you would get an H-1B until October next year because of the quota. Unless you have a US master's degree.

You would have to get legally married in order for your wife to get a derivative visa.

Would you happen to have any information for me? Here is my situation:

My boyfriend lives in NYC and I was looking into teaching at a private school there. I have a few interviews this week.
I have a bachelor's degree in Psychology from Toronto. I have my teaching certificate from Buffalo, NY and my masters in education from Buffalo, NY as well.
What do I do and how long will it take? What are my options? I will ask the school about this during the interview, but what if they won't do it? What if it takes too long etc.

J-1 or TN-1. The paperwork on the school's end is about as difficult either way, but it's not that hard. J-1 can have a longer validity period, but there is a proposed rule to extend TN-1 to three years, so I'm not sure which one is better. Whichever one the school is the most comfortable with I guess.

Actually CIS does recognize Canadian common law relationships. As long as the Canadian Province recognizes the marriage as valid, CIS will honor it.

I had a case last year where the E-2 investor had a common law wife in Ontario and she was issued an E derivative without issue,

Actually someone pointed out in another thread that "co-habiting" partners can go in as B-2 indefinitely anyway, there is a special rule for them. On an H-1B an H-4 cannot work anyway, so there is no real disadvantage to a B-2 entry other than possibly confusing the USCIS officer. If the co-habiting partner wants to study, it's easy for Canadians to get F-1 status so that doesn't really matter either.
