Initial family inclusion is recommended, but it does not guarantee matching decision dates. Keep relationships, ages and any later change subject to specific review.
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. Beyond cost, each family member is vetted individually, so a spouse's prior immigration history or a child's medical record is its own admissibility question. Family provisions are stated in terms of people and their relationships, so the documents that matter are civil-status documents rather than anything describing what was purchased. After successful vetting, current terms request a US$2 million gift for a corporate-sponsored principal; the corresponding individual-principal gift is US$1 million, and eligible included relatives have separate published amounts. The official materials contemplate qualifying family inclusion with separate charges for each joining spouse or unmarried child under 21, and the current terms should be verified rather than assumed.
