The filing of the I-526 petition will not effect the F-1 status of the daughter. If the daughter is in the U.S. and maintaining her F-1 status in the U.S. and the I-526 petition is approved then the F-1 student can apply for adjustment in the US.
If the F-1 student is outside the U.S. when the I-526 petition is approved then the student cannot enter the U.S. under F-1 student status and claim a non- immigrant intent when her real intent is to apply for a permanent residency status in the US.
