food stamps..

Moriah
1. If I get food stamps in one state and in a couple months move do they transfer or would I have to reapply?
2. On online job apps sometimes they ask you if you've had food stamps in the last (blah blah date), do you have to answer, does it matter?
3. Do you have to list it for taxes or anything??
4. Is there any stipulation to not getting them?
