Yes, you are able to apply for a green card through EB5. The funds may be raised domestically, however, the sourcing of the funds needs to be shown. There are other investment visas available as well. Please feel free to consult me.

Feel free to contact us for a free consultation to have your questions answered.
Your options depend on what visa you were brought to TX on, and what you will be doing (employment) once the company is closed. As far as your permanent resident status, you may want to find out if it has been filed and check the status on it. Contact my firm or an experienced immigration attorney of your choice can guide you through the process and discuss your options.
Each lawyer has their own rates, and you must consider that filing fees (currently around $465) are sometimes included in the fees. Please feel free to contact myself or an attorney of your choice to discuss further.
