In terms of future travel to the US, you're probably already in a tight spot........you need to apply for a visa (rather than the online ESTA) if you have a conviction. Can take months and good chance of refusal anyway I believe.
Obvious maybe, but get legal advice from a lawyer who knows that country's laws. Ignoring it could have significant long term impact if you ever plan to travel abroad (not just where it happened) from entry refusal to arrest/detention. Good luck.......
