No. A support document is one part of preparation. The actual immigration steps and work authorization remain separate.
Keep the proposed assignment current
Review substantive duty, site or supervision changes rather than relying on a reference written for a different arrangement.
A change in duties, work location or the identity of the actual employer can affect the basis of the case and should be reviewed rather than assumed to be covered by the original filing. Freeze and date the version used for petition preparation, then create a comparison listing changed duties, locations, supervision, and customer sites. The applicant must complete one continuous year abroad within the applicable three-year lookback, work for a qualifying related organization and demonstrate special or advanced company knowledge for the proposed duties. Separate information gathering from hands-on diagnosis, code changes, configuration, or customer delivery, and obtain advice about the employee’s location and existing status. A launch-driven posting frequently runs longer than intended, and an extension is a fresh set of steps for every person holding permission through the principal, not an administrative renewal.
