International migration is at an all-time high, with the largest numbers migrating to the US, making this an ideal setting to study migrant health. While previous studies have shown that foreign-born individuals in the US tend to be in better health than the native born with regard to several health outcomes, less is known about such advantages in terms of cardiovascular disease and diabetes, which are some of the leading causes of morbidity and mortality worldwide. In this paper, we highlight the main existing resources available for the study of cardiometabolic health among US immigrants that researchers have yet to fully utilize. Despite the limited literature on migration and cardiovascular disease and diabetes, there are several data sources that can be used to better understand the importance of location exposures and of predispositions to these diseases.
