Philippine immigration authorities have started deporting more than a thousand undocumented Chinese nationals who were found to be working for Jack Lam’s illegal online gambling operations in the country.

In November, a total of 1,316 Chinese nationals were rounded up during a raid at Fontana Leisure Parks and Casino in Clark Freeport, Pampanga. So far, the Bureau of Immigration said it has sent home 259 of the Chinese nationals in several batches since December 20, The Philippine Daily Inquirer reported.

Atty. Ma. Antonette Mangrobang, spokesperson for the bureau, told the news outlet that the remaining 1,000-plus Chinese workers will also be sent home “as soon as possible.”

“All of them have deportation orders already,” Mangrobang said, but pointed out that speed of the deportations depends on how soon the Chinese nationals can get a ticket to fly home. The Chinese workers are also required to secure clearances from the National Bureau of Investigation to prove they do not have pending criminal cases in the Philippines.
