I just want to clarify why this is not so straightforward. It really depends on how the term “illegal alien” is defined.

Before BBB July 4, Medicare covered the following groups:

- Refugees

- Asylum seekers

- Immigration parolees

- TPS holders

- DACA recipients

Under the Trump administration, the following groups are now considered illegal aliens:

- Asylum seekers with pending claims or those whose claims were denied

- Immigration parolees

- Certain categories of TPS holders (for example South Sudanese TPS ended Jan 6 2026 so all people under that protection are ordered to leave)

- Certain categories of DACA recipients

And the above people are probably registered for medicare with full name and address.
