1. My story begins like this: I was working for company A, got stamping in May2007(in canada). Came back to US, changed to company B. Got laid off on Feb 27th, 09. In order to have a valid status I got married on Feb 15th and got my H4 legally on March 20th, 09. Two weeks back a miracle happened, got a job through company C and applied for PP H1b, received it last Thursday. Now, I am planning to go to India for a week in June, 09. Tough having a valid H1b stamping prior to the H4-H1, do I still need another H1b stamping?
PS: I do not have H4 stamping.
Ans. I do not believe you need a new visa stamp because you already have an H-1 visa from another employer. You should be able to travel with the same visa (and a new H-1 approval). If you had ever been out of status, you would have been well-advised to get a new stamp. In your case, you appear to always have maintained status (albeit H-4 for a brief while). So, I see no issues. As always, double check with your H-1 lawyers.
PS. I would be careful how I phrase my thoughts if I were you.

Ans. I know you do not mean that :-), but the govt might think otherwise.
