I am afraid to apply for DACA. How do I know that USCIS won't use this information in order to find and deport me?
 
United States Citizenship and Immigration Services (USCIS) has stated that they are only concerned with deporting those who pose a threat to national security or have committed fraud on their DACA application. If you meet all of the requirements and do not have a criminal record, it is highly unlikely that USCIS will come after you. In a meeting with Director of USCIS, Alejandro Mayorkas addressed us personally and stated that USCIS is invested in the success of DACA. The US government has spent millions of dollars in implementing this program so that those who qualify for it, will apply and receive its benefits. USCIS wants to use DACA as an example of how they are capable of creating and implementing new immigration policies.
