These visas could allegedly be converted to a work permit upon arrival to the Saharan country.
The DFA issued an advisory on Friday reminding the general public to obtain a working visa/permit prior to departure for Egypt.
It also said that irregular workers, or those who do not have proper documents, do not have the same rights as regular ones and could become victims of abuse or unlawful practices.
The Egyptian government could also impose penalties to those who will violate their laws.
"The public is encouraged to apply through agencies accredited by the Philippine Overseas Employment Administration and to abide by all the rules and regulations of both the Philippines and the host country," the DFA said.
