Old Guilty Plea, New Deportation Fight: Ohio Court Rules
An Ohio appeals court ruled in October 2026 that a non-citizen cannot reopen a 1998 guilty plea over deportation consequences after waiting nearly two decades to challenge it. Thanh Luu, who faced removal proceedings since 1999, filed multiple motions to vacate his pleas — and lost every time for failing to appeal earlier denials. The ruling is a stark reminder that delays in challenging a conviction can permanently end an immigrant's legal options.
A Vietnamese immigrant spent nearly 30 years trying to undo two guilty pleas from 1998 — pleas he says cost him his right to stay in the United States. On October 15, 2026, Ohio's Eighth District Court of Appeals rejected his latest attempt, ruling that he waited too long and raised the same arguments too many times.
Thanh Luu pleaded guilty in Cuyahoga County in 1998 to felonious assault and carrying a concealed weapon. The trial judge did warn him at the plea hearing that a conviction "may have the consequence of deportation" for non-citizens. Luu said he understood. The U.S. government started removal proceedings against him in October 1999 — meaning he knew about the immigration consequences by then. He did nothing legally until 2017, when he filed his first motion to vacate (cancel) his guilty pleas. The trial court denied it. He did not appeal. He tried again in 2025, raising the same arguments plus two new ones: that he had no interpreter at his 1998 hearing, and that Ohio's 2022 change to concealed carry law should wipe out that conviction.

The appeals court said no on all counts. The legal principle blocking him is called res judicata — a Latin term meaning a matter already judged. Under Ohio law, once a court decides an issue, you cannot keep re-filing the same claim. Because Luu raised the immigration-warning argument in 2017 and never appealed the denial, the court said he gave up his right to raise it again. The interpreter argument was also blocked — the court said he could have raised that on direct appeal back in 1998 but never did. On the concealed carry claim, the court noted Luu gave no legal reason why a 2022 law change should apply backward to a 1998 conviction.
What this means for immigrants with old convictions
This case is a warning. If you have an old criminal conviction and you believe the court did not properly warn you about deportation consequences, the clock is running. Filing late — and then failing to appeal a denial — can permanently close the door. Ohio's R.C. 2943.031 requires courts to give non-citizens a specific deportation warning before accepting a guilty plea. If that warning was missing or wrong, you may have grounds to challenge the plea. But you must act, and you must appeal if you lose.
What to do
- If you have any criminal conviction — even an old one — and you are not a U.S. citizen, talk to an immigration lawyer now. A conviction that seemed minor in the past can trigger removal proceedings (the formal process to deport someone).
- If you believe the court did not give you the required immigration warning before you pleaded guilty, ask a criminal defense attorney about filing a motion to vacate your plea — and do it as soon as possible. Delays can and do kill these cases.
- If a court denies your motion to vacate, appeal that decision. Luu lost his case largely because he never appealed earlier denials. Missing an appeal deadline can permanently bar you from raising the issue again.
- If you are already in removal proceedings (immigration court), tell your immigration attorney about any old criminal pleas immediately. They need the full picture to build your defense.

This case shows exactly how res judicata destroys otherwise valid immigration arguments. Under Ohio R.C. 2943.031, a non-citizen has a statutory right to a specific deportation advisement before pleading guilty — and if that advisement was defective, a motion to vacate can succeed. But you must file promptly and, critically, you must appeal every denial. If you have any old conviction and are facing removal proceedings, bring both a criminal defense attorney and an immigration attorney into the case immediately — the two areas of law are deeply intertwined and one lawyer rarely covers both adequately.
Frequently Asked Questions
What is the deportation warning Ohio courts must give non-citizens before a guilty plea?
Under Ohio law (R.C. 2943.031), a judge must tell a non-citizen defendant that pleading guilty may lead to deportation, being barred from re-entering the U.S., or being denied naturalization. If the judge skips this warning, the defendant may have grounds to cancel the plea — but they must act quickly and appeal any denial.
What does res judicata mean for immigrants trying to reopen old cases?
Res judicata is a legal rule that says once a court decides an issue, you cannot keep filing the same claim. In immigration-related criminal cases, this means if you filed a motion to vacate your plea and lost — and did not appeal — you generally cannot file the same motion again. Ohio courts apply this rule strictly to successive motions.
Can a change in state law wipe out an old criminal conviction that affects my immigration status?
Not automatically. In this case, the court rejected the argument that Ohio's 2022 concealed carry law change should cancel a 1998 conviction. To use a new law retroactively, you must show legal authority that the law applies backward in time. Without that, courts will not apply it to old cases.
I have an old conviction and I am now in removal proceedings. Is it too late to do anything?
Not necessarily, but time matters. An immigration attorney can review whether the original plea was properly handled — including whether you received the required immigration warning. A criminal defense attorney may be able to file a motion to vacate if grounds exist. The sooner you act, the more options you have.
