I have worked for a company in Florida for four years on H-1B. During my fifth year I asked HR to file for my Labor Certification because I wanted to remain in US permanent. They filed my Labor from their Atlanta Office and then subsequently closed the office. I received a notice of findings on my case. My company was asked to file a fresh labor from where they had an office. If they had notified the DOL about the closing this would not have happened. I grew frustrated and switched companies and found a new employer willing to file my labor. They have treated me very well and I have gotten my labor approved and I-140 and I-485 filed. Im glad I didn't wait for my sixth year to make a decision. So those of you still trying to sort out your own frustrations please keep your head up and keep trying.
