If you want someone to visit you in the United States but he or she doesn’t have the resources to do that then you can take the financial responsibility of that person. You would need to prepare some documents to financially sponsor a visit visa that would show that you are financially sound and will take care of the money matters.The documents for sponsoring a visit visa are mentioned below.
Write an invitation letter to your family or friend and invite him or her to visit the United States of America. This letter is a personal letter, you can see a sample letter here.
Affidavit of Support: Form I-134:
You must fill Affidavit of Support From I-134 form for everyone you are sponsoring financially. If you are sponsoring your parents, you should fill two separate forms for them (being on safe side). You don’t need to notarize it, just sign it.
Copy of the Sponsor’s Passport:
Photocopy should be of the passport page with all information.
A letter from your workplace on the company’s letterhead showing your designation, joining date and yearly drawing salary.
Write a sponsorship letter addressed to the US consulate requesting to grant the visit visa to the applicants.
Bank Verification Letter:
You must obtain a bank verification letter from your bank providing that you have an account with that bank. It can show the date when you first opened the account, the total balance you have. Its better to ask the bank how much time they would take to issue a letter so you can plan ahead.

You must attach copy of your last income tax returns or W2 forms. If you own a business or self employed then you would need copy of personal tax return.
Visa or Residence Documents:
If you are a visa holder then you must attach the copies of the visa (H1/L1), H1 approval form (I-797) and I-94. If you are a green card holder or a citizen, then, copy of those documents are require instead.
Please attach your recent pay slips / salary slips, better to attach past 6 months pay stubs.
Bank statement of last 6 months showing a good amount of money to sponsor a trip of your relative or a friend. Please be advised that you must maintain this balance in your account and if you have a recent chunk of payment deposited in your account you must have a good explanation for that.
