H1B or LCA Amendment?

[QuestionV]

Background: I started working with the current employer on OPT in summer of 2012. I continued working for the employer on H-1B from October 2013. My H-1B is valid till September 2016.

 

Just this week, my job title changed from Staff Engineer to Project Engineer I. It is the next level position in the company's career path. However, there has been no change in job responsibilities and the salary raise was within the same wage level on original LCA / H-1B. Original LCA / H-1B petition have Staff Engineer as job title. The responsibilities may change later this year once I obtain professional licensure but they haven't so far.

 

Employer, office location, etc. all are the same.

 

I am curious if any changes to petition are required: new LCA or H-1B amendment?

 

Thanks.
