The medical examination is a mandatory step in an immigrant visa application. However, many individuals still encounter errors that delay results or require a re-examination. Choosing the wrong timing, lacking necessary documentation, or failing to prepare a complete immunization record are the most common mistakes. This article compiles practical experiences on this topic from this specialized immigration law office, based on the latest regulations of the US Consulate. You will have full information regarding costs, locations, and vaccination requirements to prepare optimally before visiting the designated hospital.

US immigration law requires all immigrant visa applicants to undergo a medical screening at a facility designated by the Consulate. You cannot choose another hospital or clinic on your own initiative, no matter how reputable it is. This is a mandatory step that cannot be bypassed—there are no exceptions for any case.
The answer is yes. Every immigrant visa applicant, including infants, must complete the mandatory medical screening for immigration applications according to the categories specified by the CDC (US Centers for Disease Control and Prevention). The Consulate will refuse to process an application if it lacks a valid medical report. Even if you possess premium health insurance or check-up results from a private hospital, those documents are not recognized as substitutes.
Note: The entire medical examination and vaccination catalog must strictly comply with the mandatory regulations of the US Centers for Disease Control and Prevention (CDC).
Applicants must receive their interview appointment letter from the NVC (National Visa Center) before scheduling a medical appointment. The ideal timeframe is 3–4 weeks (21–28 days) before the interview date. This interval is sufficient for processing results while ensuring the validity of the application.
The medical report is valid for 6 months from the date of the examination. Therefore, examining too early—such as immediately after submitting Form DS-260—can cause the results to expire before the interview. This can lead to additional costs and multiple trips.
Special Notice: For individuals at risk for pulmonary tuberculosis who require sputum testing, the report is only valid for 3 months instead of 6 months.

You must prepare all of the following documents when visiting the designated medical facility:
You must pay the full US immigration medical examination fees, which include mandatory categories such as blood tests and chest X-rays under regulations.
How is the US Immigration Medical Examination Conducted?
Depending on the volume of applicants registered for the day, the medical examination typically lasts approximately 2–3 hours. The immigration medical examination includes the following content:
The minimum clinical screening categories include: examinations of the eyes, ears, nose, and throat; checks of the extremities (arms, legs); heart, lungs, and abdomen; lymph nodes and skin.
The medical unit designated by the Consulate will notify you when results are available. Typically, the processing time to return medical examination results ranges from 3 to 10 days.
In certain cases requiring monitoring or supplemental laboratory tests, processing times may be extended, and the medical examination results may be transmitted directly to the Consulate. The attending physician will discuss the findings with the applicant and provide guidance on necessary treatment requirements (if any). If treatment is required, the applicant must undergo it at facilities designated by the Consulate.
In practice, many applications are delayed not due to the process itself, but because the applicant failed to fully prepare their medical history or prior treatment documentation. Cases involving a risk of pulmonary tuberculosis, communicable diseases, or unclear medical records usually require supplemental monitoring before results can be transmitted. In such instances, the medical facility will require additional laboratory tests or treatment before forwarding the report to the Consulate. The file will only proceed with adjudication once all medical criteria under immigration regulations are fully satisfied.
Other common errors include:

The mandatory medical examination fee for immigration applications currently ranges from 210 to 389 USD per person, depending on the age of the individual being examined.
This price scale already includes the clinical examination, basic laboratory tests, and chest X-rays. Some facilities accept card payments, while others only accept cash.
If tuberculosis is detected, you must complete a 6-month treatment course before receiving results. The cost of tuberculosis treatment medications can range approximately from 1,500,000 to 3,000,000 VND, depending on the treatment regimen and monitoring timeframe.
The cost scale may be adjusted periodically based on the medical facility’s policies. Applicants should check directly on the official websites of the designated institutions to update the latest price charts.
Under regulations, applicants are only permitted to perform the US immigration medical examination at official medical facilities designated by the Consulate. The list of approved hospitals is available on the Embassy website.
Currently, the US Consulate designates two official facilities to perform US immigration medical examinations in the Southern region:
In the Northern region, the International Organization for Migration (IOM) is the sole entity designated by the US Embassy to perform US immigration medical examinations:
Applicants must schedule their examination appointments in advance, particularly during peak seasons for permanent residency applications.
Upon completing the medical examination, applicants will be directed to receive supplemental doses of mandatory vaccines (if they have not completed them under regulations).
The following vaccine types are mandatory for immigration purposes:
Vaccination costs: approximately 150 USD per person, applicable in scenarios where the applicant has not received the full schedule of mandatory vaccines required under regulations.
According to updates from the US Centers for Disease Control and Prevention (CDC), the COVID-19 vaccine is no longer included in the mandatory immunization list for immigrants as of May 2023. However, vaccination requirements may be adjusted based on epidemiological situations and the latest guidance from US health authorities.
Bring your childhood immunization records so the physician can cross-reference them. Many individuals have received full doses but lack documentation, forcing them to be re-vaccinated, which causes waste and increases the risk of side effects. If the record book is lost, obtain a certification from the health station where the vaccinations were previously administered.
Immigration medical policies may change depending on epidemiological situations and medical recommendations. Some vaccines that were once mandatory have been updated or removed, while health monitoring criteria remain strictly enforced. Staying informed about the latest changes helps you avoid redundant preparations and ensures your medical report complies with regulations at the time of submission.
Things to Note Before and During the Examination Day
Regarding Diet and Laboratory Tests
For family-based files, multiple members are often scheduled for examinations at the same time to ensure a synchronized processing pace. In scenarios involving young children or elderly individuals, the physician will evaluate health status based on age and medical history. For employment-based categories, basic medical requirements remain unchanged; however, applicants must proactively arrange to satisfy all medical criteria applicable across all immigration categories. Understanding the medical requirements by application category helps applicants minimize errors and avoid unnecessary incidental adjustments during preparation.
