If it turns out that Justin is convicted of crimes in any country, and he decides to apply for a green card, he will have to explain his criminal record. Applicants for certain types of immigration benefits, such as asylum or a green card, must disclose any prior criminal convictions. This is true whether the crime occurred in the U.S. or in any other country. If a person doesn't disclose his or her criminal record, it is likely that the government may still find out. Prior criminal convictions won't necessarily prevent someone from getting approved for immigration benefits, but it is important to talk with an attorney before applying to be aware of any risks. The list of crimes that can impact someone's immigration status is very complicated, and an experienced attorney can help determine whether someone's record will cause problems.
Could the White House petition result in Justin's deportation? It's very unlikely, because Justin's crimes likely aren't serious enough to qualify him for deportation. He also has many fans in the U.S. who would like him to stay! Having broad support from your community can be important in certain immigration settings. Under certain circumstances, the law allows the government to exercise discretion, and decide whether a person should be allowed to stay in the United States despite some mishap. Again, it is important to talk to an attorney before requesting prosecutorial discretion. An attorney can help you figure out whether your circumstances would qualify you to apply, and whether you would have a good chance of success.
