Who should I apply for immigration forms?

Question

Is there a complete list?

Answer 1

Yeap, it exists. Here the link of a lot of forms  ---> form i-131a <----  helped me a lot when I myself was an immigrant and wanted to legitimize my living in the US to citizens. Correctly compiled form, not a lot of time and now you understand that absolutely everything is in your hands! Have a nice day!
