Because Puerto Rico [1] is a commonwealth, there are no U.S. embassies or consulates here. Several countries are represented locally by consulates, though, including the United Kingdom (Torre Chardon, Suite 1236, 350 Ave. Chardon, San Juan, PR 00918, 787/758- 9828, fax 787/758-9809, btopr1 [at] coqui [dot] net) and Canada (33 Calle Bolivia, 7th Floor, Hato Rey, San Juan, PR 00917-2010, 787/759-6629, fax 787/294-1205).
