Murray says her aunt applied not once but three times for a visa, each time denied because the U.S. government says it’s not satisfied the aunt will return to Vietnam, fearing she’ll become a refugee.

The aunt is said to have provided proof of financial and family ties that would compel her to return to Vietnam, and, her two brothers have been visiting here for two weeks.
