A passport change does not itself guarantee a different chargeability result or eliminate case review.
Plan from actual eligibility and availability
Assess material changes using official case facts. Vetting, admissibility, visa availability and the residence process remain separate from obtaining a travel document.
Follow current official instructions and keep records of communications and submitted documents, and identify what the household would change if a later step requires more information or takes longer than expected. The current FAQ says the process should take weeks if documents and the visa interview are completed promptly, but that statement is not a guaranteed deadline and visa availability can still cause waiting. Because terms and processing arrangements for a developing program can change, re-verify them at each decision point from the official program information, and involve a licensed U.S. immigration attorney throughout. Payment and even successful vetting do not confer status; the applicant works in the United States only when admitted in a status that permits it, which for permanent residence means after the immigrant visa is issued and used. Record the date of each submission and of each request received, and calculate a response deadline from the document itself rather than from a general recollection of how long such things take.
