Politeness is now such universal term that everyone can not ignore in communicaction, particularly in request-making. As a result, politeness strategies for requests are developed to apply in interaction depending on social contexts in each culture. This study is done for the sake of finding the differences and similarities as well in politeness strtegies for requests made by English and Vietnamese native speakers under the impact of age, gender and social status so that finally some suggestions for making requests are given to Vietnamese learners of English to have suitable responses to those from the English culture. Two versions of questionnaires: one for VNS and the other for ENS are delivered to collect the data for analysis. Both group have the same number of paticipants (30 for each). The study’s data analysis is based on statistic method, comparison and contrast as well. Consequently, the result of the study shows that there are both similarities and differences in choosing the politeness strategies for requests made by VNS and ENS. Also, the three factors of gender, age and social status more and less affect their selection of request strategies.
