2. PREPARE YOUR EVIDENTIARY SUPPORT
In order to obtain any of these three visas, you will need to ease the U.S. government's concern that you are simply using these papers as a cover for traveling to America and then remaining there indefinitely. The application process will, to greater and lesser degrees depending on the length of your intended stay, look for you to demonstrate a bona fide non-immigrant intent. There are several things to which you can point to demonstrate this non-immigrant intent.
Explain your financial ties to your home country.
If you have wrapped yourself up in business dealings at home, the U.S. consular division is less likely to think that you will ditch all of that sunk cost simply to run off to America. Bank accounts, stock certificates, bond coupons, or any other items that can prove your financial ties will be helpful to have handy. Of course, having a home or other assets in your home country is also excellent evidence of non-immigrant intent, and you should have proof of those assets available.
On a related note, be prepared to prove your employment prospects in your home country if you can. If you have a letter from an employer offering you a job upon your return from America, or you currently have a job from which you are taking only temporary leave, make copies for the Embassy officials of any documents that can verify these facts.
Obtain proof of family ties, if you have any, in your home country.
Of course, if you have a spouse and children at home, this will assuage the Americans' fears. Even having other immediate family members will help, so gather some evidence that describes your relationship to them, including their names, residences, occupations, and ages. Affidavits from your relatives will help.
Proffer some evidence of your ties to your home community.
If you participate in any social, political, religious, or cultural organizations, bring some proof of that. Again, the idea here is to demonstrate your connection to your home country.
You may be asked to furnish these materials as part of the written application for a visa, or during an interview about that application. Bring multiple copies of them with you every time you go to the U.S. Embassy.
