Hi

My wife and I are Indian passport holders.

I was working in Vietnam until recently and we are still based here until the end of June. Now I have taken a break from work and we would like to travel for tourism to China and Mongolia before we start working again.

We might be travelling to Singapore in July and I was wondering if it possible to get the China and Mongolia visas in Singapore itself.

Our planned trip is -
Singapore
Beijing
Mongolia
Beijing
Xian
Shanghai
Singapore

Can we apply for the double-entry visa for about 45-60 days in China, and about 20 days in Mongolia. - in Singapore?

Regards
ravi
