Earlier reports had said the Sri Lankans in the group had complained they were being hunted down by the Sri Lankan police, who had pursued them in Hong Kong in 2016, and could not return to their country.
Tibbo made a decision to go public with their identities previous year after learning that movie director Oliver Stone had found out about them and would incorporate their role into his film on Snowden, released in October.
The asylum seekers have complained publicly several times of having been persecuted in Hong Kong by Sri Lankan authorities, although the Hong Kong government has never acknowledged this claim. A Sri Lankan couple with two children, a former Sri Lankan soldier, and a mother from the Philippines allowed Snowden to hide in their cramped apartments for several days.
Human Rights Watch also urged the Canadian government to "intervene swiftly and protect them" following the rejection of their petitions in Hong Kong.
The Hong Kong government issued a statement claiming the asylum claims were being handled in a "fair, impartial and efficient manner", and that it found "no substantial grounds for believing that the claimants if returned to their country of origin, will be subject to real and substantial risk of danger".
"We're talking about people who entered Hong Kong years apart from one another, who submitted asylum claims years apart from one another, and yet all these decisions are coming at the very same time".
The family of Sri Lankan asylum seeker Ajith Pushpakumara, a former soldier from Sri Lanka who has been living in Hong Kong since 2003, housed the former USA intelligence contractor for about two weeks in 2013, shortly after he leaked classified documents that showed the extension of mass online surveillance by the American and other governments.
"They could be arrested any time, the children could be separated from their parents", Snowden said in the video.
Tibbo said their cases had been rejected because their home countries were deemed safe. Snowden then re-emerged and unsuccessfully sought asylum in South America, eventually ending up in Russian Federation.
Marc-Andre Seguin, a Canadian attorney representing the families in their applications to move to Canada said the refugee families have been targeted.
"The solution is Canada", he said, adding the country is one of a handful of jurisdictions that permit a review of refugee applications from people who haven't been screened by the United Nations.
"The Hong Kong government "has repeatedly tried to question the four adults about their involvement with Mr Snowden". They have two weeks to appeal, BBC reported on Monday. I was tortured in my country.
