H1B and TN Visa Combination Scenario

I am a Canadian citizen currently residing in India. My husband is travelling to Us Chicago in march on H1B. My plan is to join him in Chicago in April for few months and then search for job there itself. Do i need to apply for H4 visa or i can enter US on Canadian tourist status. Also once i get job then do i need to go out of US and come back on TN visa status ?

I don't know if you are following the news but DHS is currently trying to pass a law that will revoke the right to work of H4 visa holders.

I guess if that's the case you are better pursuing the TN visa route.
