It removes the age-out question but nothing else. Your husband is a derivative who receives conditional residence with you and must be included in the removal-of-conditions filing. Each of you needs civil documents and medical examinations at the consular stage.
One derivative, the same steps
A spouse is a derivative beneficiary of the investor petition and may immigrate with or follow to join the principal, receiving two-year conditional permanent residence. He does not need to invest, participate in the business or meet any qualification; he does need a valid marriage certificate, a passport, police certificates for the countries where he has lived, and a medical examination at the consular stage. When the time comes to remove conditions on Form I-829, he is included in her petition, and if the marriage has ended by then he may file separately in some circumstances.
Without children there is no Child Status Protection Act arithmetic to track, which removes the main reason to hurry a filing. Once he holds conditional residence he can work for any employer without a separate authorization; before that, as a Canadian visitor, he cannot. If he expects to run the agency's day-to-day operations as its administrator, he cannot do so until the residence issues.
