So, about three months ago, there is a housemate left and another one replace him (this one is recommended by the housemate who left). That time I was aboard, so I was only informed that he was moving in out unit. I also quickly inform the landlord, but not in detail, telling the landlord that I will update soon. When I come back to the unit, I asked him to show the documents. However, he said that he was just graduated and was working at NUS and told me he will send me later. That time I was really busy that I forgot to ask him again (I barely see him outside his room), until last night when the ICA officer did random-check our unit and catch him away. They called me today and want to interview me next week about the incident of overstay.
I am really worried that will affect my job and housing status. Is it considering "harbouring overstay" ? I am very confused and don't know what to explain to them, since I always do the right thing (checking IDs and inform landlord) before, but I am just too stupid and busy to forget it this time. Please anyone have experience or knowledge about it, can you give me some advices?
