Wow that’s alot of cope just to say nothing at all. The only strawman here is yours, and citing news stories alleging individual cases of malfeasance by federal officials is irrelevant. No one has suggested that the ease of immigration or lack thereof is material to its legality or lack thereof.
Having your green card revoked is actually quite difficult but not impossible. A green card may be revoked based on numerous grounds including: fraud, criminal activity and/or abandonment.
1. Fraud: If a green card holder lied, omitted relevant information or committed any fraud during the application process, his or her green card may be revoked. For example, marriage fraud is grounds for deportation. If a foreign national marries a U.S. citizen solely for the purpose of obtaining a green card, his or her status as a lawful permanent resident may be revoked.
2. Criminal activity: The INA details specific crimes that would subject a non-citizen to deportation. Crimes involving moral turpitude, aggravated felonies and certain drug-related crimes can all subject a lawful permanent resident to revocation of their green card.
3. Abandonment: An individual may lose lawful permanent resident status by intentionally abandoning it. You may be found to have abandoned your status if you: (1) move to another country and intend to live there permanently; (2) remain outside the U.S. for an extended period of time (more than 183 days), unless you intended this to be a temporary absence; (3) fail to file income tax returns while living outside the U.S.; and/or (4) declare yourself a “nonimmigrant” on your U.S. tax returns.
