I am a Jamaican citizen living in the US undocumented over 20 yrs now by my father wanting a better life for me. Unfortunately he did not file citizenship for me because he had taken me away from my abusive mom, but ended up getting life in prison. I am wanting to go back to Jamaica because I am not getting through with my immigration because I have no solid proof on where I entered the US per USCIS. My question is, will I be able to travel back to Jamaica without a passport? I do not have one I only have my Jamaican birth certificate and US driver license. Help please. Thank you.
If I were you I would not leave the US without first talking to a US immigration lawyer. Depending on your age and other circumstances (your arrival in the US and your father's status in the US, for example) you may have other options that you are not aware of. If you leave the US you will trigger a 10-year ban, after which you will probably continue to have difficulty getting a US visa.
That said, to answer your question:
will I be able to travel back to Jamaica without a passport? I do not have one I only have my Jamaican birth certificate and US driver license.
Generally, no, you won't be able to do that. To go to Jamaica, you would normally therefore need to get a passport. You can do this at a Jamaican consulate or embassy in the US. For example, the Consulate General of Jamaica in New York has a page about adult passport renewals and one about new applications.
