IN my letter on the boy Ngo Van Ha (South China Morning Post, February 23), there was a typographical error.

The sentence, ''There can be no doubt that Ha is an orphan with a family willing to accept him in Vietnam and with a strong desire to join his family in Los Angeles,'' should have read, ''There can be no doubt that Ha is an orphan with no family willing to accept him in Vietnam . . . ''.
