申请到加拿大的旅游签证，准备邮寄材料到加拿大驻纽约领事馆。 网页上说提供回邮
服务。在提供USPS的EXPRESS MAIL 的时候，发信人写加拿大驻纽约领事馆的地址吗？
？？多谢。
Below is information from Canadian consulate website:
USPS has recently changed its "flat rate" policy for "Express Mail" or "
Priority Mail" envelope, be sure to specify that the envelope will be mailed
from New York City.
