This research analyzes demographic characteristics, socio - economic characteristics, language ability, national pride, perceptions of Thai people and Thailand of Koreans in Thailand. This research was written based on findings from a sample of 458 respondents who were selected from the population of Bangkok, with a standard deviation of ±4.6 p at 95% confidence level. The data collection was conducted from August to October 2013, spanning over 90 days. Because of the limited nature of this survey, it may not be fully applicable to the entire Koreans in Thai society. Analyses included an overall frequencies analysis as well as chi-square analyses using variables such as gender, income and age. I propose three suggestions from this research. The first suggestion is the need to open free lecture for the lower income groups who do not possess a good Thai language ability. The higher income groups could speak Thai more fluently (23.95%) in contrast with the lower income groups(10.35%). However, the rate of positive perceptions for having a mind to learn(very much and much) was higher for lower income groups(low, lower-middle, 81.45%) in contrast with the higher income groups(64.6%). Language is the vital instrument to live a successful life abroad. So I suggest that Korean Embassy in Thailand or Korean Cultural Center in Thailand or the Korean Association in Thailand should open free lectures for the lower income groups who do not possess a good Thai language ability. The second suggestion is the need to develop the program for reducing the income gap. Respondents above middle income groups comprised of 73.8% of the total sample population, and the lower income groups made up 26.2%. Economic disparity among the respondents can cause some social disharmony. In this regard, I suggest that Korea government develop the program to reduce the economic disparity or support for settlement for social harmony. The third suggestion is the need to provide systematic educational and cultural programs to better understand Thai culture and Thai people. 81.7% of the respondents strongly agreed or agreed to the statement “I like Korean?”, while 54.5% among the respondents expressed positivity(strongly agree, agree)towards the statement “I am favorable to Thailand.” While Koreans take pride in their own national pride overall, their perception of the Thai is lacking. In this regard, I suggest that Korean government provide systematic educational and cultural programs to better understand Thai culture and Thai people to raise the awareness.
