Is someone wanting to be imported back to America? 
The doctors… I’d say in most of the marriages that I know of between a US citizen girl and a Pakistani citizen guy, the guy is a doctor. Probably because the guy can speak English very well. He has less loans, if any, so more stability. Once he passes those USMLEs and gets into a residency, he starts making money (whereas those who went to med school in the US have to suffer debt for several years).
