Hello there,
The first question I have is how old you were when you got arrested? If you were a minor when this happened, then you will have no criminal record and shouldn’t have any issues traveling to the U.S. because it won’t show up anyway. Now, the U.S. border randomly conducts a check into whether or not a visitor has a criminal record, but you’ll be taking a bit of a chance if you have anything on your adult record.
If you’re in doubt about whether or not you have a record, try doing a criminal record check online to see if you have a criminal history and what crimes are listed (if any).
MY next question would be, what was the crime? The U.S. has different admissibility requirements and allows people to enter with certain criminal records, but naturally not everyone can freely enter. If you see anything on your record, do a Google search about whether or not you would be admissible to the U.S. or not with your record. For example, if a person has a DUI on their record, they are admissible, but crimes involving moral turpitude (major fraud offences, sexual assault, murder, etc.) would make a person inadmissible. Under some offences, there are exceptions depending on the sentence given and whether or not there was a conviction and what sentence was given.
Recap:
• Figure out whether or not you were considered a minor
• Do a criminal search on

• Check of your offences will make you admissible or inadmissible into the U.S.
I hope this helps and best of luck!
