Dear Sir/Madam, Hope this email finds you well. I am reaching out to you to know the procedure for claiming social security contribution one-off refund. I am an expat working on a local contract in MNC company in Vietnam but now I got a job in Singapore and I am moving out of Vietnam. I and my employer had paid social security contributions increased rates from Jan 2022 therefore please let me know the process so that I can claim one off and then return my work permit and TRC to authorities. Thanking in advance for your response. Best Regards, Salman Rafiq
