What we can do now if my I-94 expires?

Significantly more information is needed in order to analyze your immigration legal situation. Are you already a Lawful Permanent Resident who is considering applying to become a naturalized citizen? Are you a nonimmigrant for whom a spouse filed only a Form I-130 petition for relative alien? What is your immigration-related history, including method and date for entering the U.S.? How old are your U.S. citizen children? Etc. There really is no substitute for consulting with an immigration attorney who, after learning all of the relevant information, could advise about immigration-related eligibilities, options and strategies and could offer legal representation in the often complex application process.
