Writing something for 5 min
Then said magical sentence
Consulate : your visa is approved sir. Have a nice day.
Me : Thanks you so much sir.

And I left from there.

My suggestion is that don't say you are going for productive work and don't use work work at all.
And make sure you convince him that you are going for non productive work. And be prepared for all type of questions.
