This paper investigates the stereotypes about the Brazilian people built by the foreign students in the Portuguese as a Second Language Course at PUC-Rio. The objective was to identify the qualificative expressions in relation to the Brazilian culture - specially represented by the adjectives, verbs and adverbs -, analyse these evaluations from the students before and after having been immersed in Brazil, and show how they can interfere in the intercultural communication. The analysis revealed that: (i) a big part of the foreign students had built a stereotyped image of the Brazilians and Brazil; (ii) the stereotypes have to do with the information collected by the students in the media, i.e. TV, newspaper, internet and also through Brazilian friends, Brazilians in general and relatives; (iii) the images built by the foreigners are positive in relation to the Brazilian and negative when it comes to Brazil; (iv) the positive attitude in relation to the image of the Brazilians and the exposure to the Brazilian culture make the foreigners interaction in the intercultural situations with Brazilian students easy.
