Hi can you guys please post your updates? I am in a similar situation but slightly different. My MIL came first time in 2016/08, has a date until 2018/08 (so still valid)...but she went back home and when she returned in 2017/05, the officer only gave a stamp no date. I am worried that it means her 2018/08 validity is void now and only had a validity of 6 months since 2017/05? this means she overstayed for over 5 months! Please post your updates and suggest what I should do now! thanks all
