Join us for Welcoming Week!

The County of San Mateo’s success depends on making sure that all residents, including immigrants, feel welcome here.  This week, we honor the spirit of unity that is bringing neighbors together across San Mateo County. Led by the national nonprofit Welcoming America since 2012, Welcoming Week serves as the annual campaign and celebration to showcase the growing movement of communities striving to be more welcoming places for all, including immigrants. Join us in celebrating Welcoming Week! Together we build stronger communities where residents have the opportunity to contribute at their best. Click here to see the events schedule for this incredible week!
