No need for bilingual foster families??

My husband and I have two biological children. We are bicultural and bilingual. Our primary language at home is Spanish. We were under the impression that there was a high need for bilingual/bicultural foster families. We live in an urban setting where Latinos make up about 16% of the population. We completed our certification classes and paperwork over 7 months ago. Our certifier took many months to complete home visits, the last of which she did two months ago. in total it has been 9 months since we began the process. Our certifier called me today and stated that there would be little chance of any children within the parameters of what we requested, who need foster care that come through their office; as such it would not be worth completing our home study. We had said our preference was a school-age child that was able to speak Spanish, as that is the primary language spoken in our home. I asked if other counties may refer kids that might be a good fit for us but she stated this would not be a possibility, that it had to be within our county. We were told that if we were willing to open our parameters up to English only speakers that we could be certified. Our concern is that a child who does not understand our primary language will not feel very comfortable in our home. We also want to continue to speak Spanish with our children so they can benefit from being bilingual. I am concerned that knowing this certifier it may be just an excuse for not wanting to complete the home study report. We are confused and a bit frustrated that no one told us this from the start. It would have saved everyone time and resources. If anyone has any knowledge or experience with this type of situation I would greatly appreciate the input!Thanks!
