In addition to the above-mentioned paperwork filed with the petition, a second Affidavit of Support will need to be filed. This one is different from the first one filed for the Embassy, as it is mandatory and the sponsor has to prove that they have sufficient income to support their alien spouse. There are set minimum incomes that must be met to qualify as a sponsor.

If the US citizen spouse is not earning sufficient income they can seek the assistance of a co-sponsor. Both sponsors will be financially liable for the alien for up to five years in the event that the alien is unable to find employment. In other words, US Immigration does not want to allow immigrants in to the US who then becomes a drain on the US welfare system.

Where a co-sponsor is required then the attorney will charge an additional fee for the extra work that will be required in preparing the affidavit. However, if no additional sponsors are required then no fee will be charged for the US spouse sponsoring their alien spouse.
