答：中國口岸簽證與有些國家“落地簽”類似，是辦理簽證的一種“方式”或者說“途徑”，而不是像“商務(wù)簽證”“旅游簽證”等是簽證的一個種類。無論是口岸簽證還是“落地簽”，各國都依據(jù)各自法律設(shè)定相應(yīng)的申請條件和辦理程序。根據(jù)中國有關(guān)法律規(guī)定，持普通護照外籍人員有緊急入境需要、來不及在駐外使領(lǐng)館辦妥來華簽證的，可申辦口岸簽證入境。外籍人員申辦口岸簽證，可由本人或邀請單位提前向口岸簽證機關(guān)提出申請，或在抵達口岸后現(xiàn)場向口岸簽證機關(guān)提出申請。為便利申請人順暢辦理口岸簽證，避免申請人在抵達口岸后因具有法定不予簽發(fā)簽證、法定不準入境等情形，無法獲批口岸簽證入境，影響行程安排、增加經(jīng)濟時間成本，建議外籍人員提前向擬入境地口岸簽證機關(guān)預(yù)申報，經(jīng)口岸簽證機關(guān)初步審核同意后再抵達口岸辦理簽證。外國旅游團申辦口岸簽證的，應(yīng)由負責組織接待的境內(nèi)旅行社提前向口岸簽證機關(guān)申請。

截至目前，中國在國際航線較多、外籍人員入境量較大的口岸均已開展口岸簽證業(yè)務(wù)，覆蓋全國72個城市的99個對外開放口岸。（主要口岸簽證機關(guān)及聯(lián)系方式可在國家移民管理局官網(wǎng)查詢）

Answer: China’s port visas are similar to the “visas on arrival” of some other countries. The term refers to a “way” or “method” to apply for visas, rather than a specific type of visa like "business visa" or “tourist visa”. Regardless of the names, every country sets corresponding application conditions and processing procedures according to its laws for foreign nationals to apply for visas in this way.

According to the relevant Chinese laws and regulations, foreign nationals holding ordinary passports, who have urgent needs to enter China but do not have enough time to apply for visas at Chinese embassies or consulates abroad, can apply for port visas for entry. Foreign nationals applying for port visas can submit applications in advance to the port visa authorities by themselves or through inviting parties, or apply on site upon arrival at ports in China.

To facilitate the applications,avoiding situations where applicants are unable to obtain approval for entry due to legal reasons such as being legally ineligible for visa issuance or entry upon arrival at ports,which may affect travel arrangements and increase economic and time costs, it is recommended that foreign nationals submit their applications in advance to the port visa authorities in the intended destinations, obtain preliminary approval from the port visa authorities, and then go to the corresponding ports for applying for visas. For foreign tourist groups applying for port visas, the Chinese travel agencies responsible for the reception should apply for them in advance at the port visa authorities.

As of now, port visa services have been provided at 99 ports in 72 cities nationwide with a large number of international flights and a high volume of foreign nationals entering China. (For the details of the major port visa authorities in China and their contact information, please visit the official website of the National Immigration Administration.)

Answer: A foreign national who plans to apply for a port visa at a port visa authority is required to submit his/her valid passport or any other international travel document, along with relevant supporting documents that evidence the urgent reason(s) for his/her entry into China. Once the visa is issued, he/she may enter China from the port where the visa application is made. As for the supporting documents, a foreigner entering China for urgent business activities, for example, shall submit the inviting party’s invitation letter explaining the business purposes, details of emergency, and main itinerary arrangements, as well as relevant proof of the emergency.
