A funding agreement does not itself establish residence or work permission.
Plan from the actual process
Review confirmed stages and unresolved requirements. Capacity to pay or a desired move date does not guarantee approval or visa availability.
The current official page says the expedited process should take weeks after the application and processing fee are received, provided requested documents and fees are submitted promptly; a visa interview, admissibility and visa availability still apply. Recheck the framework before acting, particularly if the proposal or family circumstances change, and avoid locking in housing, employment, or school decisions around an assumed approval date. Official material describes the process in terms of weeks, but that is a description rather than a commitment, and vetting, visa availability, an interview, or a further document request can each extend it. The Gold Card process seeks permanent residence through EB-1 or EB-2, while TN requires temporary intent, so an immigrant filing may affect the TN assessment even if the official Gold Card terms permit parallel processing. The actual outcome depends on the required submissions, vetting, eligibility, admissibility and visa availability, and general or promotional statements about processing are not an individual commitment.
