Thanks friends for r helps
i have asked the Embassy , and they told me , must you have the I134 affidavit of support , or you must have 65.000dollars!!!!!!!!!!
As britsimon says above, $65,000 is pretty high but assuming you have a large family of say 6-8 people then you're in a bit of a situation and you'd need financial backup to get you through.
The expenses pretty much start from the day you filled in the DV application waaaaay back in October as follows. To elaborate on britsimon's post as follows:
Internet Fee - whatever $$$ it costs in your country
Courier (FedEx/UPS) - around $40 (I'm guessing)
Documentation Procurement Expenses - can be anything from $100 to $1,000 depending on where you are and if you have to pay legally or bribes to get these documents quickly.
Medical - between $150 to $600 (on average) per person depending on what vaccines each person requires.
Visa Fee - $330 per person
USCIS Fee - $165 per person
Air Fare - approximately $800 to $1,500 per person depending on the airline for economy class
Luggage Trolley (yes Luggage Trolley!) - about $5 per trolley depending on the airport (last time I was there it was $5)
Taxi - if nobody is picking you up, you'll need a cab. A three hour trip can hit $400 (that's what it cost me from JFK to Allentown in Pennsylvania). A trip within the city is perhaps $20 depending on where in the city it is and traffic. Naturally if you have a family then you'll need two cabs.
Accommodation - a decent (and I mean like a basic hotel) would be about $60 to $100 per night per room. If you're lucky you could get away with special offers. If you don't find an apartment or alternative accommodation and are in a hotel for a month then you're looking at around $60 x 30 nights x 2 rooms (assuming) = $3,600 and by the way if you have a family you can't shove them all in one hotel room because of health and safety regulations.
Apartment - a decent single bedroom apartment in the suburbs (depending on which state) can be anything between $900 to $1,700. For example a single bedroom apartment in Allentown (Pennsylvania) is around $1,100 with utilities and the same kind of apartment in Maryland or Virginia is $1,700. If you have a family you'd need at least two rooms so your rent can hit around $2,000 or more. If you're in a city then the rents are way higher. Having said that and to reiterate britsimon's post; you'll have to pay a month or two deposit and rent up front so you'd be looking at not less than $6,000 depending on where you are.
Transportation - if you're in a city you can get by with public transport which isn't expensive. If you're not in a city you will definitely need a car to move around and be able to go to the supermarket or pharmacy etc. A garbage bin of a second hand car would be around $4,000 depending on its condition and year or a good second hand vehicle can be around $18,000. New cars start from $20,000 upwards depending on what make you buy.
Food - everyone has to eat and the stomach knows no shame or limitations so you will need to feed yourself and your family unless you decide to live on soup for 6 months and one loaf of bread every two days. A trip to the supermarket to buy the basic groceries, fruits, veggies, shampoo, shower gel etc. for a month could be around $300 to $500. Eating out at restaurants is not an option if you're financially restricted because a meal for 4 people at Outback Steakhouse (for example) easily hits $80. Alternatively a restaurant like Saad's (in Philadelphia) which is a halal restaurant is cheap and the food is good and you'd get away with a meal for a whole family at $25.
So as my friend britsimon says quite correctly, this process takes money and quite a decent amount of money to be safe and many people are naive of this and get a rude awakening when they get to the USA and in your case if you don't have a sponsor then you either need to find a sponsor for an I-134 or have enough money to let the consular officer know you won't be a public charge.
Remember the US Government is sitting on a deficit right now and doesn't need more expenses in the way of immigrants who are at risk of becoming a public charge.
Simon - please correct me if I am mistaken anywhere.
