Hi Sanjay
That's good job offer. Please dont hesitate to take the job offer if they are paying you good salary i.e. local allowance + Dollar remitted in India. There are mixed notions again n again am repeating that if you are good to your co workers, employees under you, driver and house help. Nothing to worry at all. You can certainly plan to bring your family also. We have an Indian School in Ilupeju and you will find Indian grocery easily available here.
Just keep open mind and be alert and all is fine. Try to take accommodation in Ikeja or Suruleru as they are bit more safe area than Ilupeju, Ikorodu, Ojota etc.
All the best to you and welcome to Nigeria.
People here are very friendly if you reciprocate it properly.
Regards,
Briju
