I can't find where to start a thread on this so I'll just do it here.

I'm in the US and have no green card or work papers. My dad did me wrong and didn't get my green card. I've been here the last 21 years unable to work a regular job and mostly homeless. I've decided I should just return to Nigeria so I can at least work, etc. But I have questions:

How do I go about doing this? I don't have my Nigerian passport anymore and would have to get another one. Also, who do I talk to here in the US? I want to be back where people are generally comvivial or hospitable. There are plenty of opportunities in America, but they usually come at unforeseen costs. I don't want to be here any longer as not even the churches here are willing to lend a hand. Everyone here is selfish and if you're not selfish before you come here, you will be after.

Any help or advice would be appreciated. Thanks.
