Never apply for PRTD in Abu Dhabi. I applied in April 2016 and got rejected PRTD reply in June 2016 by VFS. I used to visit VFS everyday morning and evening daily for 2 months. At the last, I went to Embassy office, luckily I managed to speak to officer and after 1 week got the reply. If your case is not eligible for PRTD do not apply in ABu DHabi.
VFS takes money and does not give any direction or timeline and your passport is left with them.
I am still repenting and facing the problem of rejected PRTD applied in ABu Dhabi VFS.
I strongly recommend you to withdraw PRTD application in Abu Dhabi office.
