Indonesian Reside in Taiwan

Jhoel, actually, if you don’t have HK residence permit in HK, it’s not easy for you to get the L type in HK.
You can try to find a travel agency in Taiwan to apply the L type for you.

Hi, I'm Sherly from Indonesia who currently studying in Taiwan. i want to ask about your previous question.. Are you already know how to go to China for holiday purpose without going back to Indonesia? can we apply visa China in Hongkong?
Thankyou before

That is technically up to whether the Hong Kong CVASC accepts your application. IIRC they now have an online registration system so it should be easier to get a number (although you still have to wait once inside). However keep in mind that reports for applying a visa often comes from those with citizenship in developed countries so your experience May differ.
