Frequently asked questions

Is this reference library an official source of law?

No. Ace Immigration is a private law firm. Statutes, applicable regulations and governing decisions are primary authorities; these explanations help locate them but do not replace them.

Does a publication date certify attorney review or current law?

No. A publication date records publication, while an event date records a historical milestone. Check subsequent developments. Russian text is an informational translation, not an official legal version.
