Birth certificates showing place of birth for every family member, current passports, marriage and any divorce records, and evidence of prior immigration filings that might already carry a priority date. As conditional residents they may work for any employer, so the spouse can manage the hauling company's office or drive, but the statute excludes the investor's spouse and children from the count of qualifying employees, so their positions add nothing to the ten.
