You already changed the NOC to the approproate one. There's nothing you can do unless they specifically ask you for some additional documents.I really hope it's just a minor thing and that they will check and release it ASAP... is there anything we can do proactively? I mean, I'm not sure what other documents I can send to prove I was in that company for more than 3 years and that I was performing those duties on the letter... my boss signed that and it has all the contact details... telephone, email, etc...
