Very good topic.
I would suggest another business in USA, from my own experience. Due to recent foreclosures and economic recession caused by banking industry, the defaulted (Foreclosed) house purchase from banks is a good investment.
A foreclosed house is a house that was mortgaged (financed) by banks during early 2000s at high market value, after economic recession, the housing values in most US metropolitan areas have gone down (excluding, California, NYC, Virginia, etc. housing markets).
I live in Midwest, where you can buy a foreclosed house of 1500 to 2000 square feet, for around $25,000 to $50,000 ( that is CORRECT, only 25 Lakh to 50 Lakh Pakistani rupees), in States like Ohio, Michigan, Wisconsin, Indiana. And you can fix, repair, update, remodel those houses and put them on Rent.
I have bought two houses, fixed them myself, hired some people from Craigslist to do the major fixing and paint work, and put them on rent. On average you can get monthly rental of $650 (2 Bedroom, 1 bath) house to $1,000 (3 Bedroom, 2 bath). The Taxes and insurance would be $150 to $200 per month. So you can make almost $800 profit on $1,000 rental per month. And if you have 4 or 5 houses rented, you can make a good living.
I know a Pakistani (Matric or FA Passed man from Pakistan) who now owns 20 such rental houses in my state and he has Gas Stations too. In USA, Pakistanis are very good business people they own a lot of Gas Stations (Petrol Pumps) and 7-Eleven Stores (24 hours groceries stores).
The monthly expenses vary from State to State. New York and California are very expensive to live in, as compared to Midwestern States. I initially lived in New York (Queens - from 1989 till 1996) and went to Junior High and High School there, I hated it there. Very stressful and pathetic state to live in, and a lot of foreigners from 3rd world countries of Latin America, South Asia live in New York City Borough's of Queens, Brooklyn, Staten Island, and the Bronx, and does not even look like you are living in USA. Manhattan is the only exception or Long Island, which is a nice distance away from NYC.
In my opinion, the biggest reason why most Pakistanis in USA or UK are reluctant to invest in Pakistan is mainly due to Security issues, we hear a lot of negative news on daily basis about Pakistan and kidnappings, armed robberies, murders for small things, etc. are very common there unfortunately.
Traffic is extremely bad and un-managed, even basic things like paying electricity bills, and shopping for groceries is a major pain in the back. So most people in UK and USA never return back to Pakistan for these reasons.
We love Pakistan, but risking the kidnapping of your children is unimaginable, and God Forbids that it happens to anyone.
Otherwise they would love to start some business specially in retirement years and contribute to progress of Pakistan, but first Pakistanis living in Pakistan have to straighten up the traffic mess, law and order situation, if that is done, Pakistanis can invest Billions of Dollars in many businesses and our leaders will not need to Beg to China, USA, UK, Saudi government for running Pakistan.
