How can I avoid illegal recruitment?

Deal only with licensed or registered recruitment agencies
Regularly check if such agencies are with current or valid job orders
Transact business in the official or registered office address of the agencies or recruiters
Avoid dealing with agents or middlemen. Check their profile if the agents or middlemen reach out to you.
Do not immediately pay the placement fee. Check if you are required to pay it. Pay only when the job is assured or when there is already a contract.
Ask for official receipt or invoice
Be cautious about agencies who immediately ask for payments for visa, flights, etc.
Do not apply to agencies whose published address is only PO Box. Do not send the documents only in PO Box.
Do not accept tourist or visit visas for purposes of work or employment abroad. Ensure that you have a work visa.
