Visa Application for Dutch citizens (the Netherlands)

Hello,

I'm traveling to Nepal in October on a 30 day tourist Visa. As a Dutch national, I should be able to obtain the Visa for China (the next destination on my trip) at the Embassy in Kathmandu.

Are there any limits on the length of the Visa that can be obtained via the Embassy in Kathmandu? I know that if I wanted to obtain a visa for China while I was in Vietnam, I should have a visa for 90 days. Is this also the case if I request my visa in Nepal?

Thanks in advance. Best regards,
Marnix
