A school calendar does not determine eligibility, visa availability or the actual immigration result.
Plan a contingency around the official milestones
Identify the applicable process and each person’s documents before making an unconditional move. Payment is not residence or current work permission. Keep the school plan separate from claims that the principal or family has already obtained the required status.
Nothing in the official material promises a processing time, and the route proceeds through EB-1 or EB-2 subject to visa availability, which is published in the Visa Bulletin and outside anyone's control. Recover the original message and identify its sender, issue date, requested action, deadline, receipt or case number, and official response channel. Vetting is described publicly in terms of weeks, which is a description rather than a commitment, and later stages depend on visa availability, any interview, and requests for further documents. What is not optional is re-verifying the official terms immediately before each irreversible step, because a recently created framework can publish clarifications that change amounts, sequence or eligibility. Fraud around large immigration payments tends to imitate real steps and add urgency, so a delay of a day to confirm costs nothing while acting immediately can cost a great deal.
