I find the US govt very careless at times. For instance I know guys who arrived huko juzi hawana papers and they are working in nursing homes in Seattle owned by Kenyan mamas. That can never happen in the UK today. I will give you an example of myself. I am a civil servant so not delivering services directly but the checks I had to go thru wacha tuu. They rattled my mum huko 'Ndumberi' when I asked for certain details about my grandparents.
Yaani Naijas had gone as far as bringing kids from back home, mistreating them, child labour and no schooling, beating the 'demons' out of them. Look up the Victoria Climbie case. The laws were changed. These days the police on the beat have a right to stop and ask you why the child you are with is not in school!!
