See the pattern of AORs..... still no one received AOR who belongs to London or Buffalo VO.... so i m sure it must be something related to VO this time...they have done some changes......so seems they are delaying these VO AORs delibrately....rizwan72 said:Due to randomly applications processing it seems that CIO works very carefully. So the applications with every thing solid are getting their AORs on priority basis regardless of their receipt date. For example 25th Jun applicant has received AOR. There may be other factors like busy and free visa offices but chances are slim. So applicants with some ambiguity get their more time for further checking.
Any how success rate is huge in any case roughly around 70%.
