This article looks in detail at SSI’s and APA’s rules for adults ages 18 – 64.

Requirements for Noncitizens

To get SSI or APA, you have to be a U.S. citizen, a qualified alien, or a Native American born in Canada or Mexico who has rights to cross the border. Examples of qualified aliens include people who are:

  • Lawfully Admitted for Permanent Residence (LAPR) in the U.S
  • Refugees admitted to the U.S. under Section 207 of the Immigration and Nationality Act (INA)
  • Granted asylum under Section 208 of the INA

To get SSI, qualified aliens must also meet certain other conditions. For more details about the rules for noncitizens, contact your local Social Security office and your Division of Public Assistance (DPA) office.

How to Apply

For SSI: You can apply:

  • Online (which starts the application process immediately)
  • By calling Social Security at 1-800-772-1213 or 1-800-325-0778 (TTY) to make an appointment to apply either:

For APA: You can apply by filling out the DPA Application for Services and submitting it to your local Division of Public Assistance (DPA) office by mail, fax, email, or in person.

Note: Due to COVID-19, there may be limits on in-person services. Contact your agency by phone to ask about this.

Tip: Do the applications for both SSI and APA. If your countable income appears low enough for you to get SSI benefits, you have to show you have applied for SSI before you can be approved for APA. Examples of ways to prove you applied for SSI: a letter from Social Security showing you've applied, an SSI award letter, or a proof that you got an SSI benefit for the current month.

Retroactive payments

If you are approved for SSI, you get SSI benefits for the entire time since the date you applied. That’s why you should apply as soon as possible. If you don’t have everything ready for your application, that’s OK — you can still apply and submit any missing information as quckly as possible.

If you already get SSI benefits when you apply for APA, your APA benefits will begin immediately. If you don't get SSI benefits when you apply for APA, your APA benefits will usually begin the first day of the month after you are approved for SSI or SSDI, or after Disability Determination Services (DDS) notifies DPA that you have a disability, as long as you meet all APA eligibility requirements.

Getting Your Applications Ready

To complete your applications for SSI and APA, you need:

  1. Basic facts, like your name, date of birth, and address

Social Security provides a detailed checklist of the information you need to complete the application process.

The DPA combined Application for Services also has a good list of the sorts of information you need when you apply for APA benefits.

When you apply for APA, you can also apply for other state benefits

To apply for APA, you have to submit the DPA combined Application for Services. You can also use this application to apply for other benefits at the same time, such as:

  • Interim Assistance (IA), a $280 monthly cash benefit for people who are waiting for their SSI and APA applications to be approved. Once you start getting APA, your IA benefits end.
  • Medicaid, free health coverage for people with low to moderate income. Learn more in DB101’s How Health Benefits Work article.
  • SNAP (formerly Food Stamps), a monthly benefit for people with low income that helps pay for food. Learn more about SNAP.
  • ATAP, a monthly cash benefit for families with children that also helps parents find work. Learn more about ATAP.

Tip: When you fill out the application form, make sure you check the boxes for all the benefits you need.
