An eligible derivative does not need a separate principal investment and job allocation merely to accompany the investor. A second independent principal is different.
Identify the basis of each family case
Derivative eligibility generally covers a spouse and unmarried children under 21, subject to applicable CSPA protection. Record relationships and actual case dates; payment does not universally freeze age. Immigrant-visa derivatives must enter with or after the principal. A family link does not permit two separate principal investors to double count the same jobs.
A child who is nineteen when the plan begins may be older than the limit by the time it concludes, and the way age is calculated in immigrant categories is technical enough to warrant an early, specific answer rather than a general reassurance. Age matters more than families expect, because a child who turns twenty-one before the relevant point can fall out of the derivative class altogether; track each child's date of birth from the start rather than discovering the problem at interview. Each family member’s file holds that person’s own eligibility evidence: passport, civil documents establishing the relationship, and material addressing admissibility, with certified translations where an original is in another language.
