Yes, one of the supporting documents you will need to submit is called an Affidavit of Support. An Affidavit of Support (Form I-864) is a document signed by an individual—the sponsor—which confirms that they agree to accept financial responsibility for the applicant seeking to come to live in the United States.  Although the Petitioner must complete an Affidavit of Support, a joint sponsor can also complete a second Affidavit of Support form on the applicant’s behalf. A joint sponsor is often required if the original sponsor’s income is considered insufficient.

It is important to know that the Affidavit of Support is legally enforceable.  Typically, a sponsor will retain financial responsibility until the applicant either becomes a United States citizen or is credited for 40 qualifying quarters of work under the Social Security Act.
