Employers must file an amendment of the initial h1b petition under certain circumstances!
Reasons could be organizational restructuring, significant changes in the job duties or change in work location usually require changes in petition and this can be accomplished by filing amendment and a new labor condition application.
Not all changes need an amendment petition filed. The problems of lack of transparency in corporate management making it difficult to timely comply with immigration regulations and timely file the h1b amendment can result in failure to maintain status.
Call for advice if you or your employer have questions or whether your establishment is in compliance or need help with filing the h1b amended petition.
