No. Identify actual official notices and deadlines separately from employment dates. The two may affect planning without being the same legal event.
Use the date from its authoritative source
Keep the resignation, last employment day, company funding decision and official communications on a chronology. Verify any required response directly through the applicable official channel or counsel. Do not promise residence by the last workday or assume an internal extension changes a government deadline. Current work authorization also requires separate assessment.
Use a verified milestone chart for submission, payment, screening, petition, visa, or adjustment steps. Hypothetical example: a local-radio transmitter operator is asked to relocate before any government response. Company funding, resignation plans, and current work authorization are different factual questions. Make employment decisions only after the appropriate authorization is confirmed. A gift payment under the Gold Card process is not automatic work authorization, and an employer deadline cannot replace an official decision. Do not treat an optimistic business explanation, a later-created letter, or a family arrangement as proof of a missing eligibility fact. Obtain individual advice before resigning or commencing U.S. employment.
