No. Project expenditure records and family eligibility records serve separate purposes. Organize both according to the applicable process.
Keep the household case connected but distinct
A qualifying spouse and unmarried children under 21 may seek derivative status, subject to individual requirements and applicable age rules. A strong expenditure schedule does not establish their civil relationships, complete admissibility review or grant residence. Two files with two purposes should not be merged.
The project file answers questions about capital, expenditure and jobs; the household file answers questions about relationships, identity and admissibility, and nothing in the first supplies anything in the second. Where derivative status is sought for a spouse and unmarried children under 21, the governing records are civil documents, being marriage and birth registrations, translations where required, and each person's own passport and immigration history. What goes wrong is a timing assumption: because the project has been prepared for months, families assume the personal side is quick.
Civil documents are frequently the slowest items to obtain, particularly where a registration must be requested from another country, and age-related eligibility questions for a child should be raised with counsel early rather than discovered when the rest of the file is ready. Start the civil-document requests at the same time as the project review, not after it.
