Is employer change going to be a problem when you attend for VISA?

[Oblesh]

Hi Guys,

 

My case is like below.

 

I got extesnion after 6 years, I changed my employer with this extension.

I worked with Employer A and transfered to Employer B with extension.

I am continuosly working since 2 years.I have all W2's and paystubs.

 

I am planning to go for Visa now,

 

Is employer change is going to be a problem?

Which is the good and safe place to go for stamping?

 

Thanks
