Health Check for Work Permit Vietnam (Ho Chi Minh City)

Hi,


I'm planning to apply for a work permit in Vietnam in July, and I'm currently researching the health check requirements. I have a few questions:


What are the reasons for a health check to be denied or classified as negative or unfit?


Have you had any experience with individuals receiving work permits despite not-so-positive health check results?


What are the consequences if the health check results are unfavorable? Is there an opportunity to undergo the health check again?


Thank you in advance!
