An immigration hold is placed by ICE (Immigration Customs Enforcement) when someone they believe is an illegal alien is in state custody (or federal). Most jails (I say most because smaller counties may not have an advanced webpage) or sheriff's offices have websites. Some even let you do an inmate search and it will tell you what they are charged with and if there are any holds, i.e. out of county hold, out of state hold, or immigration hold.
Once the immigration hold (or...
Unfortunately, if you did not purchase uninsured motorist (UM) coverage there's nothing you can do. Florida only requires drivers to maintain 10k in PIP (for their medical bills) & 10k in property damage.
Most states require drivers to have mandatory Bodily Injury (BI) coverage however Florida has not followed suit to the detriment of people such as yourself.
Your question leaves out a lot of important facts. I'm assuming your son was represented by an attorney if he was in federal court, either a private attorney or the public defender. You may first want to start off your inquiry by getting in touch with your son's lawyer.
If after that your not satisfied, reach out to a qualified criminal defense attorney that handles federal cases.
Finally, the only way for your son to receive a pardon is from the President of the United States.
No time limit because your attorney is obligated to hold the money in his trust account until the medical bills are talen care of, especially if you signed a letter of protection. He should be able to give you an update or an accounting on what's being held and why. Call your attorney and set up an appointment so he can explain this to you.
You need to speak with your lawyer. You shouldn't be writing a demand letter or listening to ANYONE who told you that. That is what you hired an attorney for. That is why he is going to take 33%-40% of the fee, BECAUSE THAT IS WHAT HE IS PAID TO DO!!!
If you're not happy with your lawyer that's a different story but if you have an attorney you should schedule an appointment and meet with him. Besides, your question states you went to mediation which means you are way past the demand letter...
Contact a criminal defense attorney immediately. If they asked you questions after arresting you without reading you your rights, you may have grounds to suppress your statements. Do NOT speak to anyone about the charges, ESPECIALLY the police and meet with an attorney.
Your attorney should be able to explain this to you. It's not an easy question to answer because you have not given all the facts. Yes, it is possible to get an excess verdict or settlement over the policy limits depending on a lot of different factors: could and should the insurance company have tendered the limits earlier when they had a chance to do so? Did the insurer act in bad faith? Who was the insurance company? If they're out of business and the claim is being handled by FIGA...
There is no mandatory BI law in Florida. Florida mandates PIP and 10k in property damage. The only recent change in Florida law has been to the PIP law, which mandates you must seek medical treatment within 14 days or you lose medical benefits. The other change was capping medical benefits to 2.5k unless you were diagnosed with an "Emergency Medical Condition" at which point you can receive up to 10k in medical benefits. Find out from DMV why exactly your license is suspended.
The answer is "NO" you cannot file any motions because you are represented by an attorney. It is his responsibility. If you are not happy with your public defender you can get the money together to go hire the private attorney of your choice. This will make both you and your PD happier. Good Luck.
