TM 30 reporting I have a condo. I am allowing my son to come stay there while I’m in USA for three weeks. How can he do residency reporting the Jurassic people are predatory  is there any thing I could do before he leaves?  or what is required of me 
TLDR : Answer Summary
The TM30 reporting requirement mandates that if your son stays in your condo, it must be reported to immigration within 24 hours of his arrival. However, realistically, if he is only visiting for three weeks and does not intend to interact with immigration services, there may be no practical need to report it. It is advisable to inform the condo management of his stay, as they should also report foreigners, although they often do not. In essence, for a short visit like this, many expats suggest doing nothing, especially if there are no plans to apply for an extension or engage with immigration during his stay.
