My company has an approved labor certificate for a software developer position. But the approved labor certificate is misplaced and lost. So we do not have the physical copy of the labor certificate. But after checking the immigration DOL database I confirmed that the Labor certification was actually approved. My company lost the labor certificate or did not pursue it further as the original employee had left the company. I want to use this labor certificate as I meet the requirements on the day of filling. The problem is it is lost and I do not have a physical copy of it either. Can anyone help me on how I can go about using this valuable approved labor certificate for my case using labor substitution. Any help will be greatly appreciated.
