A Filipino migrant worker and her Israeli-born teenage son were preparing to be deported from the Jewish state on Sunday night after successive court appeals failed, an NGO lobbying for children of illegal migrants said.

Rosemarie Perez was arrested by immigration officials along with her 13-year-old son Rohan on Tuesday for overstaying her work visa.

On Sunday night the two were under escort at Ben Gurion International Airport, near Tel Aviv, waiting to be put aboard an El Al flight to Hong Kong, from where they would fly to Manila, said Beth Franco of United Children of Israel (UCI).

"They're flying out tonight," she said, adding that Rohan had never been outside the Jewish state before.

Earlier Sunday a court rejected Perez's latest plea to stay, immigration authority spokeswoman Sabine Haddad told AFP.

"She has been here illegally for 10 years," Haddad said.

UCI argues that it is cruel to send Rohan -- and other children of migrants -- to a country they have never seen and where they do not speak the language.

Last week migrants, their children and native Israelis staged a protest in Tel Aviv against the policy of deporting Israeli-born children of migrants.

Ronan has "never been to the Philipines, he doesn't speak the language, Hebrew is his first tongue," said Franco, adding that it had been his dream to serve in the Israeli army.

"He sees this country as his own," she said.

Haddad could not immediately confirm that the mother and son were on their way out of the country.

She said that Rohan's father was a Turkish national who left Israel several years ago.

Many of the 28,000 -- largely Christian -- Filipinos in Israel arrived to work as caregivers and domestic workers, but according to UCI, some 600 families could now face expulsion after losing their residency status.
