How do foreign employees participate in compulsory insurance in Vietnam?

Our agency has signed a labor contract with a foreigner. In November 2024, we participated in mandatory social insurance and health insurance for the employee. Can we voluntarily participate in unemployment insurance for foreign workers? When these worker terminate their employment, will they receive unemployment benefits?

I would like to ask, for foreign workers who have terminated their employment contract, whose work permit has been expired and cannot be renewed, if they wish to receive their lump-sum social insurance, what are required procedures and documents?

How is the administrative procedure 'Settling the enjoyment of maternity benefits for employees who have left work before giving birth or adopting a child' carried out?

How are the time limit and result regulated for the administrative procedure 'Settling the enjoyment of maternity benefits for employees who have left work before giving birth or adopting a child'?

Who are the subjects, the resolving agency, and the applicable cases for the administrative procedure 'Settling the enjoyment of Health care and recovery regime benefits after illness, maternity, occupational accidents, and occupational diseases'?

What is the sequence of steps for implementing the administrative procedure 'Settling the enjoyment of occupational accident and disease benefits for first-time cases'?
