The first bit of advice is that he should have an immigration attorney work with hiim immediately. Charges such as these, if he is convicted are very difficult to get any sort of second chance by an immigration judge given the nature of the crime.
The result of the immigration ourt case always depends on the result of the criminal court case. If the criminal court case is finished and he was convicted of conspiracy to transport aliens he may have very little shot at not being deported..

Detainer stands. You will be deemed to have been convicted of an aggravated felony for immigration/deportation purposes, no bond, and you will be ordered deported. You need and immigration lawyer to go in to more details with you on the few options you have.
If the person makes bail in the criminal case, the person will be taken into immigration custody. I suggest you retain an immigration lawyer.
