楼主的脑回路清奇,你想H1b墨西哥都能让进,绿卡怎么可能还不让呢??
A foreigner of any country, who is a permanent resident of the United States
of America or of Canada, may travel to Mexico without a visa or a consular
stamp on the passport. The person should travel with the valid passport and
the valid US Resident Alien Card (Green Card) or Permanent Resident Card (
Canada).
