The present paper drew upon bibliometric analysis to tease out the advancement of foreign researches on second language sentence processing from 1993 to 2022. It was unearthed that progressive development was seen in the initial (1993-2003), growing (2004-2014) and booming (2004-2014) phases of this line. Research focuses were found to incorporate sentence comprehension, cognitive processing, neural research, bilingual phenomena and leaners’ characteristics. Notedly, these focuses were inclined to be studied in a more detailed and progressive way. Eventually, future studies of second language sentence processing will continue to explore into their contents while employing more innovative methods in an attempt to seek an interdisciplinary integration.
