students from Singapore and his Trip to Tibet

Hi! I am Tara, a Dutch student currently studying in Singapore. After finals I'll be going to Nepal from 9th of december until 16th of december. On the 20th of december I have to be in Singapore for my flight back to the Netherlands. I would be able to travel from the 5th of december and I was wondering if it would be able for me to combine my Nepal tour with a few days of Tibet. Do you think it's possible to visit Tibet for that short a time (especially if you take all the paperwork in account).

Thanks!
