请问一下，“对外汉语”专业翻译成英语是什么呢？望各位大虾赐教！！！

我们北语就是把它翻译成“teaching chinese as a foreign language”.
一般学校就这样翻，个别也翻译成"second language"

Chinese language for foreigners learning

Chinese language for foreign studies.

我们学校的这个专业就是这样翻译的

teaching Chinese as a foreign language
or
teaching Chinese as a second language
