Filing Labor Certification - previous employment history

[Robin09]

Hello.

My employer has filed my H1B visa and got approved (start date Oct 2011) and is ready to start my GC process and sent me the documents to fill the Labor certification questionnaire.

after graduation I worked on OPT for first 10 months without any unemployment days accrued. Later in 11th month I joined an e-verified consultancy and applied for OPT extension and got OPT extension approved. The e-verified consultancy has run my pay roll for 3 months.

When I filed for my H1B visa i did not mention/add 3 months work experience of e-verified consultancy and got my H1B approved.

now for the case of GC can I still ignore the 3 months experience of e-verified consultancy? or If i need to add the experience my resume will be different compared to the one I submitted while applying H1B visa...so will the different resume's affect my GC process?
