Oh dear, two very unhappy applicants.
It is very frustrating when things don't seem to be moving forward, especially when something else is going on that relies on a speedy result. I can only imagine, if everything is already safely with INZ, they are just really busy at the moment. It's a pity they can't put up a table of timings so everyone knows how long they are likely to be waiting around. Some branches around the world are busier than others and timings may be quite different. Of course, it doesn't help that it's been Labour Day weekend and a public holiday.
You can call them up or email them, but I suspect they will work at their own pace as, no doubt, hundreds of other people are in the same position and anxious to hear from them.
Michi_88, it may not be the verification of your papers that's holding things up, perhaps, as I said, INZ are just very busy and these things can sometimes take longer than they should to come through. If it is the verification that's delaying matters, perhaps there's been some holdup along the line with information coming through.
Mel, I would hope you'll be hearing shortly, as you have all your ducks lined up in the correct order and ready to go, so to speak

. Again, it could be down to pressure of work that INZ is being so slow or maybe they're checking up on your job offers and there's been a slow response from the other side. Give them a few more days and maybe then a phone call or email might be in order to check on progress and to let them know you're still waiting. This is what they say about
processing times at the London Branch.
