Many people have questions about this form when filing for an immediate relative. It is very important that this form is filled out accurately and completely.
The amount of people in the US citizen's household needs to be answered honestly. If you are claiming people as dependents on your tax returns, these people must be added to the number of people in your home. Be sure that all the required documentation accompanies this form, including federal tax returns and W2s.
If the US citizen is near the poverty guidelines, it is usually best to have a co-sponsor fill out an I-864. The co-sponsor can be any United States citizen or green card holder who is at least 18 years of age. The co-sponsor will also need to provide documentation, including federal tax returns, W-2s and current pay stubs. It is also important that the co-sponsor provide a copy of their green card of proof of United States citizenship.
Co-sponsors should be aware that they are financially responsible for the green card holder until one of two events occur. Either the green card holder becomes a United States citizen or the green card holder has worked for 10 years in the United States.
