H1B 2nd time extension and Title change With Approved I -140

[spamoh]

Hi ,

 

    Here is my situation .    

 

• On H1b since Aug 2006
• My GC was applied in July 2010 on  Job Title  as Software Engineer 
• Have approved 140 .
• Promoted to Senior/Lead Software Engineer 
• Got my first H1b extension in 2012 with no issues
• Last year 2013 , I was promoted to Software Manager but my duties are same as  Senior Software Engineer and 10 to 20 percent of management.
• Now my 2nd H1B extension  is coming up in November 2014.

Concerns 

• My Manager is adamant on applying with new title and new job description for my H1b extension , will I get query for the H1b extension ?
• What is the impact on my GC if I apply with new title and job description showing additional responsibilities
• Can I  apply for H1b extension using old job title and still work with new title in the company ?
