12月2日，美國政府發布一項攸關全球移民政策的重要聲明，宣布基於「國家安全」和「公共安全」的考量，將全面暫停受理來自19個非歐洲國家公民的各類移民申請。這項措施影響範圍極廣，涵蓋永久居留權申請（綠卡）、美國公民入籍申請、身份調整程序以及其他所有與移民相關的福利審理，連已排定的入籍宣誓典禮也在暫停之列。政府表明，這項凍結政策會一直持續，直到另行通知為止。

在這份聲明公布前夕，美國公民及移民服務局（USCIS）已於12月1日向內部員工下達指令，要求停止對19個特定國家申請人的所有移民案件做最終裁決。指令內容非常明確，指出此次暫停涉及所有類型申請表格、所有決定，包括批准、拒絕及補件要求，並且同步凍結所有入籍宣誓儀式。這等於讓這些國家的申請者在短時間內面臨完全停擺，無法進入任何法律程序的下一階段。

被納入凍結範圍的19國全部來自川普政府在6月頒布的旅行限制名單。其中12個國家被列為全面禁止入境，包括阿富汗、緬甸、乍得、剛果共和國、赤道幾內亞、厄立特里亞、海地、伊朗、利比亞、索馬里、蘇丹與葉門。這些國家多半因政局動盪、恐怖主義風險或被美方認定資訊共享不充分，而被視為安全風險較高的來源地。

除此之外，另有7個國家受到部分限制，包括布隆迪、古巴、寮國、塞拉利昂、多哥、土庫曼斯坦與委內瑞拉。這些國家雖未被全面禁止入境，但其國民的移民申請仍被列入此次審理凍結的範圍，意味著這些申請者在短時間內也無法獲得任何移民進展。

與此同時，川普政府正在研議擴大旅遊禁令的涵蓋範圍，可能將受影響國家擴大到約30國。雖然具體名單尚未確定，但政府方面坦言，未來可能會採取更嚴格的限制措施。這樣的政策方向顯示，美國政府對移民與國際旅行的安全審查正在全面升級，並可能在未來數月內影響更多國家的人民。

這項政策一出，引起國際社會以及人權團體的立即關注。外界擔憂，全面凍結移民申請的做法不僅衝擊數以萬計已在申請程序中的個人與家庭，也可能對美國的國際形象與外交關係造成長期影響。隨著官方尚未提供何時解除凍結的時間表，受影響的申請者目前陷入無法預測的等待狀態，事件後續仍備受全球關注。

On December 2, the U.S. government issued a significant statement regarding global immigration policy, announcing that—based on considerations of “national security” and “public safety”—it would suspend the processing of all types of immigration applications submitted by citizens from 19 non-European countries. This sweeping measure affects permanent residency applications (green cards), naturalization applications, adjustment-of-status procedures, and all other immigration-related benefits. Even scheduled naturalization ceremonies are halted. According to the government, this freeze will remain in effect until further notice.

One day earlier, on December 1, the United States Citizenship and Immigration Services (USCIS) had already sent internal instructions to its staff, ordering them to stop issuing final decisions on all immigration cases from applicants of the 19 specified countries. The directive was unequivocal, stating that the freeze applies to all types of forms and all types of decisions—whether approval, denial, or requests for additional evidence. It also includes the suspension of all naturalization oath ceremonies. In effect, applicants from these countries now face a complete standstill in their immigration processes, with no ability to move forward in any legal procedure.

All 19 affected countries come from the travel-restriction list established by the Trump administration through a presidential proclamation issued in June. Among them, 12 countries are subject to a full entry ban: Afghanistan, Myanmar, Chad, the Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen. Many of these countries are considered by the U.S. government to pose higher security risks due to political instability, terrorism threats, or insufficient information-sharing.

The remaining seven countries are under partial restrictions: Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela. Although not fully banned from entering the U.S., citizens of these countries are still subject to the current processing freeze, meaning their immigration applications cannot advance for the time being.

At the same time, the Trump administration is contemplating an expansion of the travel ban, potentially extending it to around 30 countries. While the final list has not yet been confirmed, officials have acknowledged the possibility of adopting even stricter measures in the future. This indicates that the U.S. government is significantly tightening its immigration and travel-security screening, with more countries likely to be affected in the coming months.

The announcement has drawn immediate attention from the international community and human rights organizations. Critics worry that freezing all immigration cases could disrupt the lives of tens of thousands of individuals and families already in the process, while also harming the United States’ global image and diplomatic relations. With no timeline provided for lifting the suspension, affected applicants now find themselves in an unpredictable and open-ended waiting period. The situation continues to be closely watched worldwide.
