Many people have stated that most schools have robust study abroad programs. It is true this is becoming a point of honor for many schools. However, it is still difficult to study abroad in the STEM fields in most schools without impacting the ability to graduate in 4 years. Also, it was mentioned that the classes are conducted in the foreign country’s language - not always true. D just returned from a semester studying at the American College of Greece, where all classes are conducted in English and all students must pass an English proficiency test. Other programs are fully taught in the native language, and some are full immersion where students live with host families rather than in dorms.
Some schools do have study abroad programs tailored to STEM majors. Loyola Maryland has a program in Newcastle geared for science majors wanting to study abroad. They also offer an Honors-based study abroad option in Glasgow. The hard part isn’t finding a study abroad program - it’s finding one where your department will accept the overseas university credits toward your major and that won’t disrupt your sequence of classes.
