No. Confirm current processing expectations from the official instructions, since an informally shared timeline may reflect someone else's specific case rather than a general rule.
Rely on the current official process for timing
Check the latest official instructions for the applicable steps and avoid setting housing, employment, or school plans around a timeline that was not independently verified for the applicant's own circumstances.
Where a family needs certainty by a specific date, that is a strong reason to have the conventional routes assessed in parallel, since TN, L-1, E-2 and EB-5 have published processing information and long records of practice. 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. The processing payment does not grant status, does not create a position in a queue that can be relied on for a particular date, and does not guarantee the remaining timeline. Decide whether to wait for official direction before spending on a medical examination or travel rather than letting a private timetable control the sequence.
