Contact friends or family that can help you get an experienced attorney right away. Things will move very quickly. You will have a detention hearing scheduled soon after your arrest to determine if you are a flight risk or are a danger to the community. This is important as the government may seek to have you incarcerated while your case is pending. From there, there are many critical decisions you will need to make, which you can only do with the advice of counsel. Often, these decisions are non-reversible, meaning once the decision is made, you cannot go back. So therefore, knowing everything possible to make the best decision for your own circumstance is critical.
