valid US visa - 請幫助說明

想去趟墨西哥。網上查到如下信息：

http://mexico.visahq.com/requirements/China/resident-United_States/

 

Starting May 1st, 2010, all foreigners, regardless of their nationality, visiting Mexico as tourists, transmigrate or for business matters will not need a visa for Mexico as long as they hold a valid US visa and arrive in Mexico from the United States.

我的H1B已過期，485pending。我算是hold a valid US visa嗎？
