Sealed indictiments are held until such time as the prosecutor decides the time is right to arrest everybody named in the indictments.

The FBI does not issue indictments. The FBI investigates crimes and turns evidence over to magistrates and / or grand juries. Those legal authorities issue indictments. Some indictments are public and some are sealed. The public ones are usually in press releases. The sealed ones are secret, often so the suspect does not know of the charges or so evidence won't be destroyed. The best way to find out about this is to NOT do it yourself.

The Grand jury is the jury that issues indictments in federal felony cases. Grand juries are only used in the United States.
Generally speaking all indictments from a Grand Jury are handed down "unsealed." It is usually only in exceptional cases (e.g.: multiple defendants for instance) where the indictments are sealed so that law enforcement can take coordinated action to arrest all the indictees at the same time, rather than the news of one or two indictments leak out and allow the remainder to flee.

All indictments are done in secret. That's why Grand Jury deliberations are not open to the public. The defense gets to see the evidence that will be presented against them during the process of "discovery."
