The SSA portal only updates when applying for SSI when a concrete status change occurs in your SSI claim.
The SSA portal does not update daily or in real time and it can take weeks to even months or years for the status to update on your SSA portal.
On the SSA portal, there are no regular daily or weekly updates or refresh cycles.
You can see the exact same status on your SSA portal for weeks or several months and even years while your SSI case is moving through review.
It's recommended that you check your SSA portal for updates for SSI or SSDI around once a month to avoid any unnecessary frustration.
Checking more than that is usually not necessary and often a waste of time.
Official SSI decisions and approval or denial notifications are also often mailed out as physical letters through the USPS before or long after the online portal reflects the final outcome.
The SSA portal website also often displays a generic "Decision Made" message without actually specifying whether you were approved or denied SSI until the actual letter arrives in your physical mailbox.
The SSA portal also tracks progress through milestones such as the Application Received, Under Review, Medical Review in Progress, which is usually the longest stage that is handled by DDS or Disability Determination Services and Pending Decision.
I would try not to check more than once a week if you can't wait once a month, although there's no penalty for logging in and checking the SSA portal for updates as it can be hard to go without checking, especially with a life changing decision like being approved for SSI or SSDI.
Many people do check more than once a day or once a every few weeks, but it doesn't update quickly and can go weeks without an update or months and years without updates.
