Does getting a PhD in a language 'L' from a non-'L' country have any drawback in case of academia? It is a common belief that "if you want to learn/study English, you must go to an Anglophone country." This belief is compounded by the fact that English teaching franchises are constantly advertising ELT as a commodity and their authority on that commodity. Some language schools do not even recruit language teachers other than the native speakers.

But, my question is about academia.

So, if someone acquires a Ph.D., say, in English  1  (linguistics) from a university, say, in Israel 2  (where the native tongue is Hebrew), would he be considered on par with a Ph.D. from an anglophone country in an anglophone country?

What kind of problems may he face if he moves to an Anglophonic country to be in academia either as a researcher or a professor?

Note: 1 might be any language other than [2] and vice versa.

Note-2: I am talking about academia.

Edit: the context is the following:   


If someone is refused a visa in any one of the “Five Eyes” countries, does this affect his subsequent visa applications in other “Five Eyes” countries?
What kind of problems may he face if he moves to an Anglophonic country to be in the academia?


No matter where he did his Ph.D., he is likely to face an extremely tight job market, with many more extremely qualified job candidates than open tenure-track positions. 

In general, to get hired, it is to his advantage to make himself and his work known to whatever sort of department he hopes will hire him. So, for example, it is a good idea to attend (and speak at) conferences in countries where he intends to apply for jobs. 

It is also a good idea to take steps to "understand" the sorts of universities where one intends to apply. For example, from what I can tell, the "small liberal arts college" model seems to be uncommon outside the United States and Canada. If he were to apply to such jobs, it would be to his advantage to learn in advance about how they operate, and to learn something about what they value.
