He can not afford these expenses, because in my Country for PPL you must have 2.7 to 3 million Bucks, and you have to pay it in advance
Anywhere you learn to fly, avoid paying in advance, whether in the USA or your home country. All too often it has happened that people pay in advance, the business takes their money and either the company closes, or there is an issue with something where the person does not get all the flying that they paid for.
.My question is that, Is there any institute or community which announce scholarships for foreigner in Oshkosh WI or in every country?
There are quite a few organisations that offer scholarships in the USA. These include NBAA, EAA, AOPA, Whirlybirds, Ninety-nines, Boeing, Airbus. Whether they will offer scholarships to foreign students, I am not sure. You will have to check their websites. Be aware also that the scholarships are rarely for the whole of the flight training. Usually it is a certain amount to go towards (not cover the whole cost of) a particular rating or area of training. Try doing a search on google for "aviation scholarships" or something like that. I'm sure you will find more than those I have listed here.
please tell me what am I supposed to do now?
Keep looking and learning and saving and dreaming. Without ambitions and goals, life can be a bit earthbound. Don't give up..
And also tell me for PPL. how much money should I have and after PPL will I get any job for experience?
That depends on the cost in the country where you are going to work on the licence. Once you have a PPL, in most countries that does not give you the right to earn money while flying. You will have to continue on to the Commercial licence for that.
OK if there is not any institute which supports poors,so I'll leave my longing desire and start making money with my father? dafinately in bus driving...
If flying is really what you would like to do, and you have made a start by learning about AirVenture and Oshkosh365, it seems to me you have plenty of initiative, and somehow, if you have the determination, you will find a way to reach your goal.
