@bhe- original passport is not mandatory to send along with your application, just send a photocopy of your passport, include the expired one as well, once the visa will be granted, they will ask you to send the original passport
@jufo - as long as the employer will send you the necessary papers, including LMO and CONTRACt, you are good to go to apply. Just make sure that everything is legal, and submit the necessary documents needed to avoid delay of your application
