No. Review the likely EB-1 or EB-2 route and chargeability early, while the application and Form I-140G evidence are being prepared. The gift is transferred when instructed after successful vetting, and discovering a category or availability problem afterwards leaves you with a completed transfer and an unresolved queue.
Sequencing a file when the queue is the unknown
Chargeability generally follows birthplace, subject to exceptions; multiple citizenships alone do not produce multiple choices. Identify the applicable country before relying on a Visa Bulletin date. Official descriptions of processing in weeks describe the program's intent; they are not a guarantee, and a qualified estimate for your own file is still possible. Nothing in the process promises approval, a date, or eventual citizenship, so build the plan around decisions, not around a hoped-for calendar.
Review the actual instructions and any available response process; an internal banking delay does not automatically extend a government deadline. An announced processing timetable is a statement of intention, not a commitment to any individual applicant, and the sequence begins with vetting rather than with payment. Do not liquidate land or move large sums until vetting is complete and the official instruction to make the gift arrives, and settle the tax timing of any sale with an adviser first.
