Given that AOR in February haven't moved an inch, then AOR in August has a long wait (from AOR to portal so far i have seen avg 3+ months duration reported and 6+ months if ADRs required. ). I know each case can be different but this assumption is based on data from this blog and vlogs shared with timelines. Ideally, if a decision is made while you are outside,(i.e portal issued) then you have to reply and let them know you are outside and provide details when you will be back so that they can hold. Renu Sharma has covered this on her vlog (

Regarding entry back, i hope you also have valid TRV visa (W-1) depending what was issued to you.
