I knew a Filipino lady who was a pharmacist in the Philippines before immigrating to the U.S. When she got to the U.S. she took the test to be licensed to practice here, failed miserably. It wasn't a language issue, her English was excellent. She had to complete two years of schooling and pass two board exams before she could work here as a pharmacist. That told me the education requirements in the Philippines were not nearly as good as the U.S.
NURSES who are educated outside usa have to pass english language test as well as usa comparability of education evaluation or test. I know one who did it not from the philippines.
