Hello reverberate007
If you look at the UKBA website using the link vinny posted you can see that they are not meeting their service standards at the moment of 70% of applications getting a decision in 5 working days & 90% in 15 working days!
It is obvious why this is - employers are getting their applications in before Tier 2 of the Points Based System goes live
& UKBA have
lots more applications to deal with with than usual.
Some applications do get refused, even from big well known employers. The more applications they have made, I am sure the better they will be at not making simple mistakes.
I would not worry, but you could get in touch with the employer. They can chase the application now it has gone past 15 days. On the other hand they may have forgotten to include something, or UKBA may have had a query & written - this all takes time.
My advice, get in touch with the employer. Good luck with the application.
Regards
