Bok choy, pak choi or pok choi (Chinese: 上海青; pinyin: Shànghǎi qīng; literally: ``Shanghai Green''; Brassica rapa subsp. chinensis) is a type of Chinese cabbage. Chinensis varieties do not form heads and have smooth, dark green leaf blades instead, forming a cluster reminiscent of mustard greens or celery. Chinensis varieties are popular in southern China and Southeast Asia. Being winter-hardy, they are increasingly grown in Northern Europe. This group was originally classified as its own species under the name Brassica chinensis by Linnaeus.

The passport card is a limited travel document, valid only for land and sea travel within North America (Canada, the United States, Mexico, the Caribbean, and Bermuda). It cannot be used for international air travel. The Department of State indicates that this is because ``designing a card format passport for wide use, including by air travelers, would inadvertently undercut the broad based international effort to strengthen civil aviation security and travel document specifications to address the post 9/11 threat environment''.

can a passport card be used for canada?
