LMIA during Open work permit

[harshrk6392]

Currently, I am working in my professional field but still finding it hard to get my ITA.

If someone is offering me LMIA offer letter so that I can increase 50 points,

1. Does that mean I have to leave my current job and work for LMIA position?
2. Does that mean I should be working under LMIA Job, during submitting all my documents or LMIA job offer is still valid if I keep working in my current JOB and use that LMIA letter to just get extra points to help my EE Profile?

Please suggest
