Thank you for your advise.
Actually I am changing my job. So the employment contract is to be signed with the NEW employer.
The new employer is hesitant to send me as an expat to Mongolia. I don't mind NOT having expat package benefits. But just would like to Employment contract to be governed by UK or Singapore law.
As in your advise, I can agree an English law employment contract. Does this mean that I can be sign an employment contract with the Bank's Representative office in Mongolia or with the Branch in the UK?
I would appreciate for your detailed advise, how I could negotiate with the Bank?
Another issue is the Pension, which I would like to continuously pay in the UK.
