Could I still obtain a marriage-based green card from Korea after being deported for a felony?
I have a citizen spouse.
If I’m deported due to a felony I committed in the U.S., I’d like to know if I could still apply for a green card from Korea afterward as the spouse of a citizen.
You can obtain a pardon for the inadmissibility resulting from the deportation and then proceed with the immigrant visa (green card) process. You would select from roughly 20 possible waiver grounds when applying for the pardon, but the important thing is not to just mechanically apply the statute — you need to research how each provision has actually been interpreted and applied in practice.
