根據最新資訊，台灣居民若欲前往烏克蘭，必須申請簽證，其中最方便且迅速的方式是透過線上電子簽證（e-Visa）系統辦理。然而，由於烏克蘭目前仍處於與俄羅斯的持續交戰狀態，外交部領事事務局持續發布高風險旅遊警示，強烈建議國人避免前往，並已在當地的民眾應立即規劃安全離境。

入境烏克蘭的主要方式：電子簽證 (e-Visa): 台灣居民可透過烏克蘭外交部官方 e-Visa 平台申請，適用於商務、旅遊、探親或醫療等目的。申請者需準備護照、照片、財力證明以及足額醫療保險（至少三萬歐元）等文件，並在線上完成繳費。申請流程包括建立帳戶、填寫電子申請表、上傳所需文件、線上支付簽證費（單次入境為 20 歐元），一般件核發約需三個工作天，急件則可在一天內完成。核發後需列印簽證，入境時與護照一同出示。

在申請和入境時，需注意以下事項：簽證效期需與停留期限一致，必須在有效期內完成入境與離境；若護照上有克里米亞或俄羅斯出入境章戳，可能遭到入境拒絕。此外，護照有效期須六個月以上，簽名欄必須由本人親簽。

重要提醒與安全考量: 由於戰事影響，烏克蘭多地仍為戰區，外交部持續發布紅色警示，建議國人避免前往；已在烏克蘭者應盡速透過安全管道離境。此外，若不適用電子簽證，仍可向烏克蘭駐外使領館申請實體簽證。

建議行前準備: 規劃行程前，務必查閱中華民國外交部領事事務局的最新公告及旅遊警示，評估當地安全狀況，確認是否適合入境。準備足夠的財力證明、醫療保險及其他入境所需文件，可避免在邊境遇到不必要的困擾。

總結而言，雖然電子簽證提供便利的申請方式，但在當前戰爭背景下，安全風險極高，台灣政府強烈建議國人暫緩前往烏克蘭，並密切關注官方公告，以確保自身安全。

According to the latest information, Taiwanese residents wishing to travel to Ukraine must obtain a visa, with the most convenient and fastest method being the online electronic visa (e-Visa) system. However, given that Ukraine remains in an ongoing conflict with Russia, the Ministry of Foreign Affairs’ Bureau of Consular Affairs continues to issue high-risk travel warnings and strongly advises citizens against traveling there. Taiwanese nationals currently in Ukraine are urged to plan a safe exit immediately.

Main Entry Method: Electronic Visa (e-Visa)
Taiwanese residents can apply through the official e-Visa platform of the Ukrainian Ministry of Foreign Affairs, which is valid for purposes such as business, tourism, family visits, or medical treatment. Applicants must prepare a passport, photograph, proof of financial means, and sufficient medical insurance (minimum €30,000), and complete the online payment. The application process involves creating an account, filling out the electronic form, uploading the required documents, and paying the visa fee online (€20 for a single entry). Standard processing typically takes three working days, while expedited processing can be completed in one day. Once issued, the e-Visa must be printed and presented along with the passport upon entry.

Applicants must note that the visa validity must match the intended length of stay and entry and exit must occur within the valid period. Passports containing entry or exit stamps from Crimea may be denied entry. Additionally, passports must be valid for at least six months, and the signature field must be signed by the holder.

Important Warnings and Safety Considerations
Due to the ongoing conflict, many areas of Ukraine remain war zones. The Bureau of Consular Affairs continues to issue red travel alerts, strongly advising citizens not to travel there. Those already in Ukraine should depart promptly using safe channels. For those ineligible for an e-Visa, a traditional paper visa may still be obtained through Ukrainian diplomatic missions abroad.

Recommended Preparations Before Travel
Before planning a trip, it is essential to consult the latest announcements and travel warnings from Taiwan’s Ministry of Foreign Affairs to assess local security conditions and determine whether travel is feasible. Ensuring adequate proof of financial means, medical insurance, and all required documents can help avoid complications at the border.

In summary, although the e-Visa provides a convenient application option, the current war situation poses extreme risks. The Taiwanese government strongly advises citizens to postpone travel to Ukraine and to monitor official updates closely to ensure personal safety.
