May be your medicals are valid till august or may be your application will complete one year in August. At least I deduced that these could be the reasons agent mentioned August to you. When I called, the agent mentioned September to me. I am 9th Oct AOR. Another time agent mentioned as security can take a few weeks, I should wait till end April and then call them. Second agent seemed more genuine to me

You can not feel low because of what agent mentioned about end date. Just keep your hopes high
