I think that if you are living with a woman, they do come and check on you at you house just to confirm that you are living there.
They came and checked on my lady and myself while I was on Non O before extension and also checked with village headman that I hadn’t caused any problems being here.
If you call paying an Agent to bribe the Immigration officers and Bank managers to do something illegal on your behalf a service, then when you get caught and kicked out of the Country and the Agent just gets a fine, then you are delusional.
