You may be able to leave the country, for business or vacation, while out on bail. If the court has instructed you not to leave the country, you will have to get permission to leave the country from the court and bail agent. It's a good idea to check with your attorney for specific travel limitations.
If you plan to go on vacation or leave the country, while out on bail, first, you should read the restrictions stated on the bond posted for your bail. If you can't understand them or are having difficulty with the legal terms, it would be best to contact your lawyer.
