溫哥華領館申請H1B，國內學曆問題

收到溫哥華領館寄來的預約確認信，其中有如下一段：

First-time "H1-B" visa applicants who earned their qualifying academic degrees outside the U.S. or Canada are strougly urged to apply in their home countries, as Vancouver consular officers are generally unable to evaluate foreign academic credentials.

請問大家有沒有從溫哥華拿到H1B的？非北美學曆是否一定回國簽證？

我的律師（在底特律）不認為這是一個值得注意的問題，但是我發現溫哥華領館反複強調這個問題，有可能和別的地方不一樣。

多謝答複。
