Kevin Fenwick has told the government he'll review the transition to the new requirements and how it affected people that have approached his office.
Saskatchewan announced in May that it was tightening its immigration rules after a request from Ottawa.
Under new rules, someone can nominate only one family member at a time instead of nominating multiple relatives all at once and those nominees need to have a job offer.
Economy Minister Bill Boyd says anyone who started the immigration process before the change was announced will be accommodated.
Boyd also says the ombudsman will only comment on the process for the change, but not on the policy itself.
The federal government oversees immigration, but allows provinces to have their own provincial nominee programs.
Immigrants in Saskatchewan have said the changes, announced without notice or a phased-in period, are a betrayal.
