In this book, we present research on health issues in diverse cultures and especially research around immigrants who came to the United States from diverse backgrounds. Hispanic and Asian Americans make up the fastest growing sector of the United States population and immigrants are often unable to access, seek, or receive health care due to several barriers. Research and also clinical experience have found that recent immigrants who migrate to the United States frequently experience a lack of access, high costs, and difficulty obtaining medical insurance along with barriers such as access to information, cultural or linguistic obstacles, and an inability to understand the healthcare system. Therefore in this book, we have tried to gain a better understanding for the readers of the experiences that immigrants undergo in the healthcare system through several research projects presented herein.
