If you are wondering what is going to happen to the work permits of Dreamers you are not alone. Those who are DACA beneficiaries will not be affected until after March 5, 2018. They have 6 months from the time the announcement was made.
President Trump stated that he is looking for a resolution for DACA from the Democrats and Republicans that will follow a lawful process. Therefore, at this time, applications filed after September 5, 2017 will not be processed. Additionally, DACA permits that expire between now and March 5, 2018 have until October 5, 2017 to apply for renewal.
