Company Name Change

[us_visa_dip]

I am all set to go to India this December 2012 to get my visa stamped on my passport. But my company just recently got bought my another company and they have changed the name of my company.

1) So if I go to India this december will I able to get my visa stamped because my current petition still has the old company name on it?
2) Do I have to ask my company to file for a new visa petition because of the company name?

Thanks
