Yes, under the following conditions:

• The assets must be convertible to cash within 12 months.
  
  
• The applicant must show that the assets can be removed from the country where they are located. Many countries have limits on cash or liquid assets that can removed from the country.
  
  
• The net value of assets must be at least five times the difference between the sponsor's income and 125 percent of the poverty guideline for the household size.

The visa applicant needs to file a Form I-864A to have his or her assets included in the minimum income level calculations. 

Financial sponsors can only include assets that are convertible into cash within one year and without considerable hardship or financial loss to the sponsor and his/her family. Examples of assets easily convertible to cash are savings, stocks, bonds and property. Sponsors may include the value of their home. They may not include the value of their automobile, unless they can show they have more than one and the primary automobile is not included as an asset.
 

No, the Form I-864 remains valid indefinitely unless evidence of failure to meet the poverty guidelines in effect on the date of I-864 filing. The consular officer will determine whether the income claimed by the sponsor and documented with financial evidence meets the poverty guidelines in effect at the time the I-864 was filed. If the income claimed does not meet the poverty guidelines, then the consular officer may request that the sponsor submit current year income information. 

Petitioners who cannot meet this level have two choices: 1) find a “joint sponsor” who will agree to also financially support the visa applicant, or 2) use the income of a household member to meet the Poverty Guidelines. These additional financial sponsors also have to submit an Affidavit of Support, proof of their income, and proof of their legal status in the United States. Remember: Even if a petitioner finds a joint sponsor or uses the income of a household member to financially sponsor a visa applicant, that petitioner must still submit an Affidavit of Support.
 

Petitioners must meet a minimum income level, called the Federal Poverty Guidelines, in order to financially sponsor a visa applicant. The Poverty Guidelines in effect on the filing date of an Affidavit of Support are used to determine whether the income requirement is met. You can find these guidelines on USCIS’s website. 

A financial sponsor, including a petitioner, must be at least 18 years old and either a U.S. citizen or a lawful permanent resident (LPR). The sponsor must also have a domicile (residence) in the United States. 

The Form I-864 asks for the financial sponsor’s household size. When calculating their household size, sponsors must include:

• Their spouse,
  
  
• Any children by birth, marriage, or adoption living in the sponsor's residence,
  
  
• Anyone else claimed as a dependent on the sponsor's tax return for the most recent year, regardless of whether they are related to the sponsor or have the same principal address as the sponsor,
  
  
• The principal visa applicant,
  
  
• Any derivative applicants who plan to immigrate within six months,
  
  
• Any other people in the United States whom the sponsor is supporting on a different Form I-864, if the obligation has not terminated, and
  
  
• Any nondependent siblings, parents, or adult children who reside in the sponsor's household who are not dependents, if they complete a Form I-864A.

A sponsor does not have to include people on other I-864s who have not yet immigrated to the United States.
