The Philippine labor visa is affixed to the passport?

Friends who have been to the Philippines all know that working in the Philippines requires a corresponding work visa. If there is no work visa, if caught by the Philippine authorities, they will be directly repatriated and blacklisted. What is the Philippine work visa like? Is it posted on your passport?

The Philippine work visa is an independent blue card, which is not affixed to the passport. In the Philippines, the visa affixed to the passport is generally a short-term visa, while the Philippine short-term visa is usually a 9a travel visa and a 9a business visa. We work in the Philippines. In addition to a work visa, we also need to apply for a labor card and a TIN tax card. Only if we hold these three cards at the same time, we are legal to work in the Philippines. None of these three cards is missing. If we lose them, we need to go to the relevant departments to reissue them.
