There are two reasons why your work visa application might get denied; either you lack documents or don’t meet the required qualifications. If your work visa wasn’t approved, you probably got a return or a refusal. A returned visa means that you have submitted incomplete documents or the program you’re applying for has already reached its quota and cannot accept more applicants.  If there is a lack of documents, you can fulfill the missing requirements and submit your application again. If your application was returned because your chosen immigration program has already reached its quota, you could only apply again once they start accepting applicants. However, if your application got refused, then the reason is the failure to meet the requirements. You can only apply again once you’re sure that you have all the required qualifications.
