Planning a trip to Mexico? Before you go, you must make sure you have all the right documents for your visa application. First, complete the visa application form with accurate personal and travel details. You'll also need a valid passport with at least six months of validity left. Next, include a recent passport-sized photo and proof of visa fee payment. Depending on the type of visa you're applying for, extra documents may be required. For a tourist visa, you might need a proof of accommodation, financial means to support your stay, or even a letter of invitation from someone in Mexico. For a business visa, a letter from your employer stating the purpose and length of your trip may be necessary. The exact documents vary by visa type and nationality, so always check the consulate's instructions before applying to avoid delays or rejection.
