MANILA - Six women dressed as nuns stood anxiously in a queue at Manila’s chaotic international airport, unaware their shoes were about to end their dreams of an illegal job abroad.

At the immigration counter, an official looked up after stamping a genuine traveller’s passport and surveyed the women.

“People were wondering, if they were nuns then why was one nun in rubber shoes and another in red shoes,” said airport immigration chief Lina Andaman Pelia.

“And all six just had one bag. You could tell they weren’t real.”

Under questioning, the “nuns” admitted they were not heading to a religious seminar in Hong Kong as claimed, rather to Lebanon to work illegally as maids.

And so — just like thousands of desperate Filipinos before them who have tried to use a dizzying array of tricks in an effort to head overseas for a higher paying job — their journey was over before it had begun.

Deep poverty has for decades driven Filipinos abroad and about nine million — or 10 percent of the population — currently work legally and illegally in a wide range of jobs overseas, according to government data.

While the government allows its citizens to work overseas, it requires them to have guaranteed labor contracts and to register with state-approved recruiters.

The government says these measures are needed because Filipinos who go abroad can easily be exploited in many ways and, at worst, be forced into crime or prostitution.

Sometimes the country they want to work in has been blacklisted completely, such as was the case with the fake nuns, with the Philippines banning people from working in Lebanon in 2007 due to security and labor concerns there.

But many Filipinos seek to circumvent these rules, with illegal recruiters often setting up the scams.

“We have economic problems in this country and sad to say, they become willing victims,” Pelia said, referring to the Filipinos who sneak overseas to work illegally.

Pelia said many prospective illegal workers simply presented themselves at airports as tourists, and it was up to the immigration officials to determine their real motive for travelling overseas.

At the immigration desk, staff look for signs to distinguish the illegal workers from legitimate tourists.

Pelia said the give-away could be a bare passport indicating the person had not travelled abroad before, or a plan to “holiday” in areas of the Middle East not normally known to attract Filipino tourists.

She said illegal workers were sometimes caught out by being unable to answer the simplest of questions, such as: “Where are you going?” or: “Who is providing for your tour?”.

But on other occasions, they put more thought into their ruse.

Pelia said the government now coordinated with sports bodies to verify which athletes were heading overseas, after some workers made it to Japan by claiming to be volleyballers bound for an Asian Games there in the 1990s.

Immigration officials are also constantly on the lookout for Filipinas seeking to head abroad for work as prostitutes who travel with fake boyfriends, Pelia said.

“Carlos,” a 35-year-old laborer, said he beat the system three years ago when he entered Japan to escort his mother on a vacation there.

When his mother returned home two months later, Carlos did not come back.

Instead, under a plan hatched by his family, he was sheltered by his sister, who already had permanent residency in Japan.
