It is quite easy to get 3-month L visas (30 days for the duration of stay) in HK the same day (drop off in the early morning) or the next day.

is it possible to get a L-visa in HK that is more than 30 days stay? like 90 days?

yes ,it is possiable .but it all depends .so we can not make sure that .some our customers got one 90 days l visa ,so ...

Hello,
=D>
Z or F and L visas is not a problem.

All my friends and me already got them with the help of one company named "Get in2 China".

For getting Z visa it is good to use their help. Those guys have some connections with companies in Beijing which capital is more then 1000000 rmb so for those companies is very easy to provide necessary documents for Z visa. With this documents you go to hong knong and get there 1 months Z visa and then come back to Beijing and extend it here for 1 year and in the future no problem to extend it without leaving the country. And you family members can get 1 year family Z visa as well!!!

The located close to DongZhiMen and BeiXinQiao.
