My “east Indian” friend who is a doctor has a son in the computer industry, a husband teaching at college and a daughter who was in the US Navy. True, when her mom came on extended visits (to care for her young kids) she did not work: But you know, you can't work on a visitor visa.
My husband, a Filipino immigrant (and WWII veteran) arranged for lots of his relatives to migrate to the USA... most are nurses, doctors or technicians. True, it includes a niece who also is on a visitor visa so she can live in the USA and care for her grandkids so her daughter can work at a rural US hospital. Eventually she will get a green card, and be eligible for medical care, but unless you ignore that those who stay home as caregivers or home makers are also contributing to the USA, you are clueless.
