An arrest warrant will be issued.
For you to handle this, you must turn yourself into the court, with or without an attorney, and try to negotiate a plea bargain on the warrant and new Failure to Appear charges, and the outstanding charges. Doing so voluntarily will result in a better outcome than you being brought in cuffs to court after arrest on the warrant. That will happen if you come in contact with law enforcement or customs anywhere in the US.
While this isn't a 'capital case', handle it right. Effective plea-bargaining, could keep you out of jail and enable you to get probation and reduced fines. Most people hire an attorney for serious cases, but this is something you should be able to handle on your own to save the money. Make sure you have a license and proof of insurance in hand when you go to court. However, if serious about hiring counsel to help you in this, and if this is in SoCal courts, feel free to contact me.
