Change of JOB on EAD

[rapged]

I got my EAD and it has been more than 180 Days since i filed my I-485. My Client wants me to join the company. The Title on my LC is Software Engineer and the title my client has for me is Sr. Systems Analyst.
Does this come under the same job classification?
About job description, my client is open to give the same as in LC in different wordings excluding (May have to travel frequently) . Please give me your valuable advise.

Thanks in Advance,
Rapged.

To invoke AC21 your I-140 MUST be approved AND your I-485 must be pending for at least 180 days. Titles don't mean much. It's the job duties you do. If the job duties are the same or similar it should be OK.
