I think I've found a loophole in the system, pay someone that is ABOUT to get their green card to marry right before they get it. And so, I would just do an adjustment of status. (and completely skip the whole process and investigations). I anticipate less scrutiny since I am not applying to get a marriage green card, I would just obtain it as an extension of my spouse's.
The other option would be to marry a US citizen abroad, wait for 2 years and apply for a permanent green card and then move go back. More time and more work...
Thoughts? Comments? Suggestions? Ideas?
Ps: this is obv and anonymous throwaway account.
Maybe someone here has been through this process recently and could detail how the process actually works.
Edit: and real life is messy. Best of luck to you regardless
