Currently, there is almost no delay for the rest of the world outside India, Mainland China and The Philippines – by the time the PERM request is approved (which in itself takes at least six months,) there should be a green card visa number ready.

Assuming no complications, the full process from LCA to a status change could take as little as a year (but 18-24 months would be a more realistic estimate).
