Please let me know when one can start working? My employer says that he has already applied for my LCA and once approved he will file the COS. As soon as he applies for COS, I can start working. Basically, he is saying no need to wait for approval. Was this the same case with you? How long it took for the COS for you? When did you start working? Also, if you have any info on the overall process/steps involved, please throw some light on this. Please help me!!
