What could you be charged with if customs seized your order of fake IDs?

I'm not sure what federal or state offense could be charged.

I would need much more information. Mail fraud comes to mind, but generally my opinion is wait to see what if any charges are involved. Frequently, the property will just be seized and the government will take no further action.

I suspect that any charges that are brought would be a violation of federal Law not State Law. Some sort of import violation. This question should be directed to an attorney with extensive Federal Practice.

A whole range of federal and state crimes. Youll learn the actual charge[s] filed against you when you appear for arraignment at your first court hearing. The prosecutor can amend at any time he feels he can prove additional or different charges. What can you do? Hire an attorney, unless you know how to effectively represent yourself in court against a professional prosecutor intending to convict. No amount of free 'tips and hints' from here or anywhere else are going to effectively help you in your defense, other than the advice to exercise the 5th Amendment right to SHUT UP and do NOT talk to anyone except an attorney about the case. That includes on this or any other web site or public forum. It also includes any communication or dealings with the store agents. Most police and prosecutors will happily tell you that 95% of people convict themselves by trying to be 'helpful and cooperative', either during initial contact, questioning, interview or interrogation. If serious about hiring counsel to help in this, and if this is in SoCal courts, feel free to contact me.

In Florida its a 3rd Degree Felony punishable by a maximum of 5 years.

They will probably all be arrested on felony federal charges. If you were one of these people you should consider retaining counsel now to protect yourself. Give us call to discuss.
