It takes approximately 2 months for the BOWP to be approved. Of course, things may change based on personal situations and current backlog. I would suggest you wait at least 1 or 2 weeks before getting too alarmed, as you are still below two months.Hi,
I am in the same boat, I applied on 28th December 2017.
I haven't heard anything since then, I call them they are still reviewing. their processing times are vague and obsolete.
