The CSPA will protect some dependents of parents who have employment-based green card petitions pending, but it will likely not protect all. We urge the USCIS and DOS to take a generous interpretation in applying the CSPA wherever possible to protect the children and keep the family unit preserved, as the U.S. Congress has expressed its intent to benefit unmarried children who are unable to get the green card because of the delays and backlogs in green card processing.
