Entry Visa

Hi there! I would like to live in Sri Lanka and contribute to the community by giving hospitality service training. I have been informed that for any application for a Resident Guest Scheme Visa or a Resident Visa, I will have to enter Sri Lanka on a Entry Visa. I have asked the Embassy of Sri Lanka in The Hague, The Netherlands but they seem oblivious...
Is there anybody who can point me to the right direction?

You can come down to sri lanka with guardian visa if you have kids and still they are schooling.

So they will give u guardian visa. Once u find employment then you can transfer you guardian visa to permanent residence.  Else come down to sri lanka on a visit visa. Then find a job and convert you visa in to company sponsorship.
