請您google Form DS-156 (nonimmigrant visa application) 第二頁, 項目38的問題第一題. 問到:"Have you ever been ARRESTED or convicted for any offense or crime, even though subject of a pardon, amnesty or other similar legal action?...."
第二頁, 項目41. "...I certify that I have read and understood all the questions set forth in this application and the answers I have furnished on this from are TRUE and CORRECT to the best of my knowledge and belief. I understand that ANY FALSE or MISLEADING statement may result in the permanent refusal of a visa or DENIAL OF ENTRY INTO the United States....."
申請綠卡也同樣會問到類似問題. Form I-485. 第三頁, Part 3, 1, b. “Have you ever, in or outside the United States been arrested, cited, charged, indicted, fined, or imprisoned for breaking or violating any law or ordinance, excluding traffic violation?
很多類的移民或非移民申請 美國移民局都會調查申請者的身家清白. 有些申請是需要案指紋做為調查. 有些只適用基本資料. 犯罪紀錄FBI都會有個centralized的資料庫, 若您需要, 您可以付費用請律師幫您申請.
基本上...您的朋友最好馬上付費請教律師把他的刑法以及移民法的問題開始計畫解決. 記得, 欺騙美國政府是非常嚴重的事情.
