No. A private estimate does not establish status, residence or permission to work.
Follow actual milestones
Keep official decisions and entry instructions separate from promotional timelines. The principal must enter before or with immigrant-visa derivatives.
Official material describes parts of the process in terms of weeks, but that is a description rather than a promise, and no one can state a completion date for an individual case. Review the actual instructions and any available response process; an internal banking delay does not automatically extend a government deadline. After submission, the applicant should expect identity and background checks, review of the eligibility basis, and the steps that any immigrant process involves before status is granted. Payment is one step in an official process that includes vetting and the issuance of whatever status the program provides; the wire clearing is not an admission. 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 legal position is unchanged by commercial pressure: lawful permanent residents generally are authorized to work, while an application, a fee receipt or a gift receipt is not that status, and no fixed additional waiting period should be invented after residence is obtained.
