If you want to invite a family member to visit you in United States, its better to invite them and write an Invitation Letter for USA visit visa with your signature on it. I am writing a sample letter below and you can change it according to your own situation. If you are inviting them for some special reason like your graduation please clearly mention that in letter. Please note, this letter its not a guarantee to increase your chances of getting visit visa however a poorly written letter won’t leave a good impression. If your family doesn’t have good bank statement and you want to sponsor them financially as well then please visit this page for more info.
