[Arihant Jain]

Hi, My L1B is approved in Nov 2016. The salary in I129 mentioned is USD 119,000. This was for location Washington DC. Now that I have been assigned to a different project, the salary offered is USD 100,000. Travel date is tentatively Mar 2017. With this decrease in salary have any impact on me on any laws / rules violation in the future? Kindly assist if there is any action that I need to take for this? Thank you
