I-140 pending and moving to different group with promotion (same job location+organ.)

[visaapplication2013]

Hi,

Not sure if this is already asked before. I could not find and if this was asked sometime ago, please reply with a link.

I am on H1 and my company is big multinational company. Filed I-140 in Dec 2012. PD is in Jun 2012.

I am at Sr Engineer position and now under same director and about 70-80% similar role (job description), I am getting a Staff Engineer position within same organization (under different manager).

I have not accepted offer yet. Need to do that soon.

I am wondering, after accepting, can I continue with current I-140 and PD. I do not want to get everything redone (wage stuff, job adv., I-140, etc.) and/or loose PD.

I know that I may need to file for H1 amend.

Can anyone please comment or share experience?

Thanks.
