Any one who were Green Card holders and committed a violent crime in the US many years back are consider as UNDESIRERABLE alien, the ICE can knock at your door and treathened you to go for voluntary deportation.I was one of those SIGA SIGA who carry a gun in my waist in the PH,but with common sense,I never touch any gun in the US at all. Most of my friends who migrated here went back to their old culture and most of them were deported on gun violations,I call them stupid and lack of common sense. To stay here longer is you have to pay huges matriculation fee to an immigration lawyer to delay your deportation. Onced your lawyer feels that your bank account is already empty he will tell you to go for a voluntary deportation hoping that you could come back after 8 years. This not True, future gov’t policy is TRUMP MERIT Base SYSTEM, if you have Ph.D. Masters Degree go to US embassy and much willing to help you. 179M foreigners applied to move to USA. Under Trump economy US is the envy of the world.
