I'm getting married and I'm on federal probation will I be allowed to leave the you.S an visit Egypt for our honeymoon?

A lot will depend on the crimes and what you were convicted of ( since Egypt may not even allow you in with a VISA depending on your crime)

But first you will have to ask your PO and get permission though them to allow you to travel out of the country

Thank you what if your crime was for possession of a firearm will Egypt allow you to visit then?

Not up on Egypt immigration, but you need to check with the local embassy ( or perhaps their immigration web site) to see what they do or do not allow.
