| Sumario: | Social media like Twitter have been widely adopted by advocacy organizations to communicate dissent and mobilize consensus during recent bouts of collective action. Viewing organizational discourse on Twitter as a strategic framing process, this study examines whether and how frames may converge among a diverse group of immigrantserving organizations after a suddenly imposed grievance, Donald Trump's travel ban, in January 2017. Topic modeling of tweet content identifies shifts in topics and frames in tweets by Asian, Hispanic, Black, and pan immigrant-serving organizations two months before and after the ban. In addition, a quantitative comparison of the number of shared hashtags and retweeted users also indicates a significant increase after the ban among certain, but not all, types of NGOs. We argue the postban Twitter discourse, hashtag use, and retweet behaviors across the immigrant groups suggest a frame alignment process aimed at communicating solidarity and building cross-group alliances that ultimately can help with intersectional mobilization.
