In my application, I wrote "Present". It was accepted
Also some members of this forum claimed that their application got returned because they wrote "present"
My advice is to write the current month and year.
windtunnel, would you mind telling which visa-office you submitted your documents to? Maybe we can get an idea which visa office does allow this practice? I also placed "PRESENT" in my current work experience and it's only now that I learned about those getting rejected, as you said, because they they did the same. It's kinda worrying. By the way, my visa-office is London CIC.
Thanks.
