I'm not sure about Studio 2015, I use 2014 with the MQ add-on, but methinks it's the same.
Ask the agency to send you Mqxliff files and you should be able to open them in Studio, translate, then save a new Mqxliff file with the translation to send to the client.
Rename .MQXLZ to .ZIP and unzip the package. Inside you'll find the MQXLIFF.
