There are several stories (published in newspapers) of Brazilians living in Portugal and being denied jobs as phono-audiologist and teachers because of their accents. Both speak Portuguese as their mother tongues. Brazilian children in Portuguese schools are also asked to speak Portuguese and not Brazilian, or to speak correctly. It is the same as if an American could not teach in UK. Or American children in UK schools being told they don’t speak English.
The funny thing is, Portuguese people love bragging about how Portuguese is one of the most spoken languages in the world. Of course, with 240 million Brazilians (and only about 12 million Portuguese).
