Language Learning To Provide Social Services

I work at a public housing provider in the U.S. and have been surprised at the diversity of languages spoken by people seeking housing assistance. I’ve learned or taught myself enough French and Spanish in the past to form some sentences, but struggle with full conversations, and lack the technical words needed to explain housing applications and options. I have used Mango Languages, Duolingo, and other smaller apps periodically. How would folks recommend I learn words and phrases that might be more applicable to a social services setting? I’m hoping at some point to expand to some of the other languages that have come up, such as Portuguese, Russian, Ukrainian, Tigrinya, Amharic, Somali, Arabic, Dari, Kreyol, Vietnamese, Cantonese, Pashto, Kurdish, Lingala, Oromo, and others… but that may be more than I can handle.
