If you move to the city after the high school application process is over, you will face some difficulties finding a school. The Department of Education Family Welcome Centers will find you a seat, but the bureaucracy can be infuriating, especially if you arrive during the summer. Try calling schools directly to determine if your child meets their admissions criteria and if there is space available. You'll still have to go through a Family Welcome Center for admittance, but it’s helpful to go in with a list of schools that you know have space and are a good fit for your child. Special registration offices for newcomers open in late August or early September.
