Yes. Just run your name on google and see all the websites that listed your arrest. You can't expunge those. They may negotiate with you and remove them for a price. The charges will show up on fbi or state crime searches but will show as dismissed.
No one can guarantee you that it won't. While you might pursue expungement to the extent possible, so that the record would not routinely appear when the general public makes a search of court records on the Internet, before you do that you should get a complete certified copy of the file and keep it with your important papers. I have heard that certain records remain available to the government for national security purposes and to the state for public safety purposes. Additional information about expungement is available at mdcourts.gov.
