I am a DACA recipient, and have not been able to renew my application due to a situation that I will not get to specific with. I am still working at a tech company and been extremely anxious this past few months about what my company might do to me since its been expired for almost a year. I've worked so hard for this and can't the fact that I might get fired due to this. Any suggestions or sources that can help on this? Sorry for being a bit generic but this means a lot to me.
