I want to visit china with my husband for tourisim . what fo i need to apply to this kind of visa ?

You should apply for a China tourist L. The process usually takes 4 working days from the day you submit the required documents. If you want to be granted with a long time, you must provide valid proof of necessary long duration in China such as the return air ticket and financial status of enough funds to cover your stay in China.

Generally, you need to provide your valid passport, fulfilled China visa application form stuck with a photo which should be recent, front view, in 48mm x33mm size without head covering, two-way air ticket, hotel booking and financal proof.

You can ask your university to provide a covering letter for you, but the bank statement will be still required, since the visa officers have to make sure that you have enough money for your duration in China.
