Among the reasons Vietnamese families seek residency abroad, healthcare typically ranks in the top three. However, this aspect is often described more simply than reality warrants.
Four Different Mechanisms
There is no single "foreign healthcare" model. At least four distinct mechanisms exist, each with different access conditions.
Tax-funded systems. Access is typically tied to residency status and paying taxes in that country. Those holding residency cards but not actually living and not paying taxes there often do not qualify, or only qualify after a waiting period.
Mandatory insurance systems. Residents must participate and pay monthly premiums, usually based on income percentage. Having residency status means you have the obligation to pay and the right to use the system.
Private-dominant systems. The state pays very little; people rely on private insurance. Residency status is less decisive; the ability to pay for insurance is what matters.
Private insurance as a residency requirement. Many investment-based residency programs require private health insurance throughout the residency period. This is an ongoing cost, not a one-time expense.
What to Check for Each Program
Can you access public healthcare, and from when. Some countries allow immediate access, others require a period of actual residence, and some only after you start paying taxes there.
Is private insurance mandatory, and at what cost. This is a condition of many residency programs, and premiums increase with age.
What about dependents. Spouses, children, and sometimes parents — conditions vary by category for each group.
How are pre-existing conditions handled. Private insurance typically excludes or imposes waiting periods for pre-existing conditions. For people over fifty or with chronic illnesses, this is the most critical question and should be answered before choosing a country.
Less-Discussed Drawbacks
Waiting times in public systems. Free or cheap public healthcare does not mean fast. In many countries, waiting times for specialist consultations or non-emergency surgery are measured in months. This is why many people in those countries still maintain private insurance alongside.
Language barriers in healthcare. This is where language barriers become most serious — very different from grocery shopping or paperwork. Large cities often have English-speaking doctors; elsewhere, it's less certain.
Insurance premiums increase with age. The cost of private insurance at age sixty differs significantly from age forty. If a program requires maintaining insurance long-term, calculate costs at future ages, not current ones.
Not all developed countries have better healthcare. Quality varies between regions within the same country. Comparisons should be made at the city level, not the national level.
Groups Who Need to Be Most Careful
People with chronic illnesses or over fifty years old. Two questions need answers before choosing a country: whether private insurance there will accept you and under what conditions, and whether public healthcare is accessible to you.
For this group, a country with easily accessible public healthcare is often worth more than a country with visa-free access to more nations. This is an entirely different comparison from counting visa-free destinations.
Three Questions to Ask Before Signing
Does this residency grant me access to public healthcare, starting when, and under what conditions?
Am I required to buy private insurance, what are current premiums and projected costs at an older age?
How are pre-existing conditions handled?
Migration advisors can answer the first question. The second and third should be asked directly to insurance companies in that country, as they are responsible for the answers.
We are not healthcare or insurance experts and do not offer opinions in those two fields. But we believe that anyone selling a residency program without asking about your family's age and health status is not doing their job properly.
