Hi, I am currently in Japan with a tourist visa for 90 days which expires on the 30th of July. I am planning to go to Shanghai by ship on the 20th of July arrival 22nd. I have already a visa for China (one entry - valid 3 months from 22nd of June to 22nd of July). The visa states that I can enter within this period and my visa would be valid from my entry day for 30 days. But it also says that I should enter before 22nd of July. Does this mean that my Visa runs out validity on the 22nd? or on the 23rd of July? Thank you for your help!
