Does anyone know what the usual customs & rules are of parents from India that're enforced on their childen when it comes 2 dating?

my boyfriend is Indian & I am a blonde & fairskinned american. His parents seem 2 like me because I’m smart & very focused on getting into med school, but they don’t seem 2 like the idea of us dating. Jay (my bf) says that race is not an issue with his parents, but, why then, do they not like the idea of ‘us’? I’m a very morally correct girl & we both want to be doctors, so, what’s the problem?
