This study describes how length of stay in a foreign country influenced personal adjustment, language acquisition, and culture learning among a convenience sample of 150 United States student volunteers participating in a short-term cross-cultural living/learning situation in Mexico. Short-term was defined as two, four; six, eight, or ten weeks. Five instruments measured anxiety and discomfort, expectations of cultural difference, changes in group membership, personal health, and language placement over the five time periods. Improvements occurred in personal adjustment, language acquisition, and culture learning for all learners regardless of length of stay, supporting short- term immersion as a viable strategy for culture and language learning.
