No. The individual sequence still depends on submissions, vetting, eligibility, admissibility and visa availability. General processing statements do not guarantee synchronized decisions.
Keep school preferences conditional
Record the actual remaining steps for each person and the lawful entry order. Ask about document validity and later-arrival instructions rather than assuming unlimited flexibility. A school start date and a paid gift belong to different parts of the plan; neither itself grants the status needed for the intended move.
Choose reversible commitments while the case is pending: month-to-month housing where possible, school enrolment deadlines noted rather than assumed, and employment notice given only when a step is actually complete. Official material describes processing in weeks, which is a description and not a guarantee; a qualified estimate from someone reviewing your file is more useful than either optimism or a flat claim that nothing can be predicted. Assess eligibility for the immigrant category that would follow before considering payment, confirm each family member's inclusion, then verify the current official terms on a recorded date. Recheck the framework before acting, especially if the proposal or family circumstances change, and avoid fixing housing, employment, or school commitments around an assumed approval date.
