For many travelers from Taiwan planning a trip to Hanoi, visa preparation is often one of the most stressful parts of the journey. Booking flights and hotels may be simple, but uncertainty about immigration procedures, visa approval, and airport entry requirements can make travelers nervous before departure. Even though Vietnam has simplified its visa system significantly in recent years, many visitors still experience avoidable problems due to incomplete paperwork, incorrect visa information, or misunderstanding the entry process. A small mistake on an e-visa application can sometimes lead to delays at check-in counters or long conversations with immigration officers after landing in Vietnam.
Today, Taiwan passport holders can conveniently apply for a Vietnam e-visa online without visiting an embassy or consulate in person. The process is designed to be faster and easier than traditional visa applications, making it ideal for tourists, business travelers, and short-term visitors. However, there are still important details travelers should pay close attention to, including passport validity, arrival airport selection, uploaded document quality, and visa approval timing.
This guide is specially written for travelers flying from Taiwan to Hanoi. It explains how the Vietnam e-visa works, the eligibility requirements for Taiwan travelers, the application process, estimated processing times, airport arrival procedures at Noi Bai International Airport, and common immigration issues travelers may encounter after arriving in Hanoi.
A Vietnam e-visa is an official digital visa issued by the Vietnam Immigration Department that allows eligible foreign nationals to enter Vietnam legally for tourism, business, or short-term visits. Depending on the approved conditions, the visa can be valid for up to 90 days and may allow either single or multiple entries.
For travelers from Taiwan, the Vietnam e-visa has become one of the most popular ways to enter the country. Instead of preparing paper documents and visiting diplomatic offices, applicants can complete the entire process online from home. After approval, the e-visa can be used at various international checkpoints throughout Vietnam, including Noi Bai International Airport in Hanoi.
One very important detail during the application process is selecting the correct entry point. Travelers arriving in Hanoi must choose Noi Bai International Airport on their e-visa application. Immigration officers carefully compare visa details with actual travel information upon arrival, and any mismatch may result in delays or additional immigration checks.

Before submitting a Vietnam e-visa application, Taiwan travelers should ensure they meet all required conditions. The first requirement is passport validity. Passports must remain valid for at least six months beyond the intended arrival date in Vietnam.
Applicants are also required to upload a clear scanned copy of their passport information page together with a recent passport-style photo. Blurry images, incomplete files, or incorrect photo formatting are common reasons why applications may be delayed or rejected.
Travel details also need to be entered carefully. Applicants must provide accurate information regarding arrival date, intended duration of stay, and selected entry airport. For travelers flying directly to Hanoi, selecting Noi Bai International Airport is essential to avoid issues during immigration inspection.
The Vietnam e-visa process is fairly straightforward, but travelers should still complete every step carefully to reduce the risk of errors. Before beginning the application, travelers should prepare their passport scan, digital photo, and basic travel information such as flight schedules and accommodation details.
Next, applicants complete the online e-visa application form. All submitted information must exactly match the passport, especially the full name, passport number, and date of birth. Even a small spelling mistake can affect visa approval or create complications during entry.
Once the form is completed, travelers upload the required documents and pay the visa processing fee online. The application is then reviewed by Vietnam immigration authorities. Many travelers prefer using professional visa support services such as https://www.vietnam-evisa.com/apply/ to minimize mistakes and improve processing efficiency.
After approval, the official Vietnam e-visa is sent via email. Taiwan travelers are strongly advised to print a physical copy before departure, as immigration officers at Hanoi Airport often request paper documents during the entry process.

Under normal conditions, Vietnam e-visas are typically processed within 3 to 5 working days. However, approval times may vary depending on seasonal demand, national holidays, and the number of pending applications.
Applications containing incorrect or incomplete information may take longer to process. Because of this, Taiwan travelers are encouraged to submit their applications at least one week before departure to avoid unnecessary stress close to travel dates.
For urgent trips, expedited processing services are also available. These services can help travelers receive approval faster, especially when flights are scheduled within a short timeframe.
Before leaving Taiwan for Hanoi, travelers should carefully review all travel documents to ensure everything is prepared correctly for immigration inspection in Vietnam. One of the most important items is a printed copy of the approved Vietnam e-visa.
Travelers should also carry the same passport used during the visa application process. Immigration officers compare passport details with e-visa records upon arrival, and mismatched information can result in delays or additional verification procedures.
It is also wise to prepare return flight confirmations, hotel bookings, and accommodation details in Vietnam. While these documents are not always requested, immigration officers may occasionally ask travelers to provide proof of onward travel or lodging arrangements.
After arriving at Noi Bai International Airport, travelers should follow airport signs directing them toward the immigration checkpoint area. This is where immigration officers inspect passports and entry documents before permitting entry into Vietnam.
At the immigration counter, Taiwan travelers must present their passport along with a printed version of the approved Vietnam e-visa. Officers may also ask several routine questions regarding travel plans, accommodation locations, or intended length of stay.
Once approved, the immigration officer stamps the passport, officially allowing the traveler to enter Vietnam. Travelers can then continue to baggage claim and customs inspection. Depending on airport congestion and arrival times, the immigration process may take anywhere from 10 minutes to over an hour.

One of the most common problems experienced by Taiwan travelers involves incorrect details on the e-visa application. Errors in passport numbers, names, or arrival airport selections often result in additional questioning or delays at immigration counters.
Another issue many travelers face is arriving without a printed e-visa approval letter. Although digital copies stored on phones are sometimes accepted, printed copies are still strongly preferred by most immigration officers, especially during busy travel periods.
Long waiting lines are also a common frustration at Hanoi Airport. During peak travel hours when several international flights land simultaneously, immigration queues may become extremely crowded and waiting times can exceed one hour. Because of this, many Taiwan travelers choose Fast Track immigration services, which provide access to priority lanes and significantly reduce waiting times.
