When to resign? After obtaining WP OR EC?

[korak]

Hi,

I am a Software Engg, in India and have got a job offer in UK. My UK employer has submitted for the Work permit in the home office on 19th August. Following are my queries:

1. Is it ok to resign from the present company in India after receiving work permit approval and prior to obtaining entry clearance?

If not, then following is my additional query:

2. I heard that the docs are submitted in VFS in India and they schedule an appointment after say 3-4 weeks. Now during this second appointment, if they keep the passport from me, can I go ahead and resign from my present organisation?

Thanks to all who reply, in advance,
