I am not tryin to scare any body but we have struggled hard, since, the day we came here. Even though we are not legally able to work here but we have few other options. Again the punishment is very harsh considering a minor crime, which is working to meet our expenses. Homeland security can just deny you entry if you have been found working on social. I suggest u to take caution if u have worked on social. Not every body has been caught or will be caught but don't take a chance if u have lot to lose or else u'll be a topic of discussion. Trust me no one can really help you out except you yourself. If you do get denied entry at the point of entry, don't hesitate to file asylum.
