Dear Luqi, just relax and don't worry bro. It is in itself a good info that your ECAS is showing 2nd line as we've started processing your application on............so stay relaxed dear. Sometimes, when a VO picks up the file, he just enters this info into FOSS / GCMS (that's how we see an up-date on ECAS)...the VO may take few days to have the case concluded. See your 2nd line appeared on Friday or Saturday....(as you reported on the forum, if I'm not wrong), then week ended-up and only yesterday LVO opened..week is still ahead and I am sure you will be celebrating your MR news with us by the end of current week.
God bless you.
