How do I find legal info on immigrating from San Salvador to the US?
The USCIS website. When you get to the main page, look on the left, and there is a "Where to Start" section that is helpful. They also have a tab for laws, and a search box. For contact information for the local office in Houston, visit this page. A local resource is Catholic Charities for Galvestion and Houston. Visit their website to see what they offer in Legal Aid.
