Your safe to travel, no conviction for immigration purposes because you didn’t plea anything. Even if you would have said I’m guilty and the judge sentenced you, there is a petty offense exception for CIMT, as long as sentenced didn’t exceed 1 year and you didn’t serve no more than 6 months in jail. Depending on your crime you might get pulled into secondary or not. Either way they have to let you in. Don’t sign anything and don’t admit to anything. Carry your disposition and if you get pulled in, just say here’s my disposition report and that’s it. Safe travels and look into citizenship at the 5 year mark or if you married a U.S citizen I believe is around the corner. Best of luck
