240 Days rule for L1 RFE extension

My l1 extension got RFE (concerting to Premium mode) and waiting for RFE details . Is it possible to stay in USA after 240 day’s but not working ?

Or is there any implication or issue if I travel out of status as reaching 240 days now ?

Yes, you can be in US and not working after 240 days. Read 240 Days Rule below
