I drove down here from NYC and never met any Punjabis(either side of border) working the motels. I've only ever encountered Gujratis from India. Personally, I don't really see the harm as most of them are older people. Most of them are too stubborn to even speak English, even If they know how to speak a little. They do take jobs, but then again they are working for their sons or son in laws. Never really had an issue with them. Now that the oil wells are drying up in San Antonio, skilled labor is migrating and I can't imagine why people would want to settle here anymore.
