After submitting the application, get a receipt with application number and track the status through this link http://www.mol.gov.qa/MLSAServices/Laborservices/LbrReqInfo.aspx Click on the seccond radio button and enter the application number and Your QID. Initially the status will be in "U", Status will change to "Y"
