When to apply for a visa
The China Consulate is suggesting that I apply not before three months prior to my proposed date of departure for China. But I want to get my mine asap so I can buy my air asap at the price I want and on the route and airline I want.
Also, I am told that they would decide which category and when the permit will expire, etc. I am supplying an invitation letter (it's on a form right now but the consulate wants the letter as a PDF document) plus the other required documents. I thought this would automatically mean I am applying for S2. Is there any way I can apply for it sooner but also make sure it doesn't expire for six months. Ideally, I want to get mine by mid-December to travel in early May.
Are their expiry dates based on when an applicant's passport expires?
Thank you.
