My China visa arrived today, have been mailed off express mail on May 19th. Since I mailed it on a Saturday, and there was the Memorial Day weekend, I am sure that it took a little longer than average. It's good for a year, and really does take up a full page of your passport. If you don't have any more full empty pages in your passport, you can request additional pages. Make sure you know your status if you are planning on traveling to the few countries that require a passport!
