H1-B second time stamping after switching employment from Full Time to EVC model consulting

[Flyerfrequent39]

Hi, I am thinking of getting my H1-B visa stamped. I already had a successful stamping back in April 2009. I need you guys' valuable input. Here is my situation:

I got first visa stamping (F1 to H1-B) in Chennai 2009. I got a 221G blue form but eventually visa was issued in 20 days.

The stamping was valid till 9th September 2011. I was working as a Full Time Employee in Company A. On July 1, 2011, Company A filed for my H1-B extension in normal processing. I received the receipt number for Company A in August 2011. I was waiting for my approval from Company A. On September 26th 2011, Company B ( consulting company working in EVC model) applied a new H1-B petition. I started working for the new client via Company B on October 1st 2011 on the basis of the new receipt number. Meanwhile, the H1-B from Company A got approved on October 7th. But I had already left the company by then, so Company A terminated my H1-B.

On October 09th, I got an RFE for the petition applied by Company B. After furnishing the client letter, my H1-B was approved on 21st November 2011. I have all the documents & all Pay stubs after I switched to Company B. It has only been over 3 months now. Will there be any issues if I go to stamping now? Is there anyone in similar situation like with successful stamping? How difficult or easy it is in Canada?

Please let me know, you input is greatly appreciated.

You will read a lot of discouraging stories of people in EVC model. So avoid stamping if you can.
