Why are almost all budget hotels in the USA managed by Indians?

Almost all small budget hotels in America seem to be managed by Indians (people from the country of India, that is). It doesn't seem to matter if it's Seattle, WA or York, PA, or Alliance, NE or Donalsonville, GA - the management is usually an Indian man and his family. Is there some network in India that matches Indian hospitality managers with hotels in the USA? How is it that they all got here to get themselves set up in hotel ownership / management in almost every community, even small communities deep in the USA? Can somebody explain? Thanks.
