IGS签证什么意思？
I-GS： I = Immigration G = Guide (or Guides). This is the non-immigrant visa classification that guides are issued in， which allows them to enter for a temporary period only and work as tour guides or interpreters while on their visas. The guide’s status of stay has many restrictions， such as being limited to certain areas/states within China and not able to change jobs once they have found one without getting into major trouble with immigration authorities. It also requires periodic re-entry visas be obtained if leaving CHina for an extended time before returning.
If you hold this classification your travel documents will state： “This passport belongs to a person who holds a valid I-Guides Visa. Holders must leave China periodically when required by Chinese law”. They look like ordinary passports but have an additional page at the back indicating their classifications， along with having a red background around the visa pages.
The I-Guide Visa can take some time to get processed depending upon where it was requested from (some Consulates have longer waiting periods than others)， so you may want to apply earlier rather than later if looking for a specific date start time.
Once you do receive it， there isn't any way to speed up its processing except maybe contacting someone higher in the office at Consulate level， although generally speaking， most applications would already be processed prior too much time passing since applying anyway. And even then…
For instance， my friend had her application go missing twice——once just days after she sent it off（the consul general himself was very helpful about tracking it down）—and again several months later， during which he spent countless hours on the phone trying to track it down herself. She eventually got frustrated enough that she went online and made a complaint against the consulate to the State Department’s website， which resulted in a personal visit two weeks later by the head of Passport Services who called myself and another American living
