To immigrate legally to the U.S. from Mexico, you can apply for family-sponsored or employment-based visas. Required documents typically include a valid passport, visa application forms, and proof of eligibility (like family ties or job offers). Fees vary by visa type, often ranging from $160 to $1,200. Processing times can take several months to years. Always verify current rules on official government or embassy sites as requirements change.
