Will a felony conviction for child abuse cause a resident alien to be deported

Certainly a legal possibility and certainly something you need an attorney for.

Will it? That's impossible to answer as to the specific individual. Could it? Certainly. The following link may be helpful: http://www4.law.cornell.edu/uscode/8/1227.text.html. Generally, if the crime involves "moral turpitude" or is an offense for which one MAY (note not "IS") be incarcerated for a period in excess of a year (and felony child abuse qualifies), it is a deportable offense. So are crimes against children.

I agree with Mr. Bassett. You should consult with an attorney licensed to practice in Florida immediately, preferrably one with immigration experience. Generally however, felony convictions may result in deportation.
