An immigrant-visa derivative cannot precede the principal’s immigrant entry. Any different proposed travel activity would need its own lawful basis and assessment.
Coordinate the task with the actual permission
Record whether the spouse intends to establish residence or undertake another activity, rather than using a household reason to bypass the entry sequence. Eligibility and document validity still need individual review. The principal’s payment or a booked property appointment does not authorize a derivative to establish residence first.
Employment-based immigrant categories generally allow a spouse and unmarried children under twenty-one to accompany or follow to join, and the official program page states how family members are treated under the framework and what additional processing fee and gift apply to each. Because a successful case is adjudicated in an employment-based immigrant category, the file resembles an EB-1 or EB-2 case: passports, birth and marriage certificates, the principal’s qualifications, and evidence of admissibility including police certificates and medical examinations at the consular stage. Derivative concepts across the immigration system extend to a spouse and unmarried children under twenty-one, and the official programme description follows the same pattern with a separate processing fee and gift for each accompanying family member.
