To gcFarAway:
Thanks for your question on why have I not yet updated my profile. Well, currently I am in the process of putting together the application, and the application has not yet been submitted. Therefore, I don't yet have specifics (e.g., application dates, service center, etc.) for updating my case.
Congratulations to you for receiving i-140 approval. In that case, could you please mention your credentials? Will appreciate your help.
