Online stock trading donot allow Canadians in US

I've opened over the years (before and after 9/11, and before and after getting GC) accounts with e-trade, TDW, sharebuilder, datek, vanguard and fidelity without problem.

Just spoke with two of my colleagues both Canadians in the US didn't had a problem opening a TD Ameritrade account.

Actually one of them have a Ameritrade and is in process to open a Scottstrade account as well. I guess they never mentioned they are Canadian Citizen.

Hi there, just wondering if anyone else has experience with this? On the Scottrade and Tradeking applications they explicitly ask what citizenship you are, so it seems difficult to circumvent without outright lieing

Cdn residents are not supposed to have a non-retirement trading account in US, and vice versa.

Cdns living in US can have such an account. One would send a W-9 to prove you are allowed.

You might not be able to set up the account on-line however. But once its up, you are fine.
