If you're traveling to Nigeria from the United States, getting your travel documents sorted out needs to happen well before you're standing at the airport with your suitcase.

U.S. citizens need a visa to travel to Nigeria. The good news is that Nigeria has moved much of its visa process online, including its electronic visa system. That makes applying more convenient, but it doesn't mean you can book a flight and figure out the paperwork when you arrive.

Your first step is determining which Nigeria Visa fits the reason you're traveling.

Nigeria has different visa categories for tourism, visiting family or friends, business activities, employment, and other purposes. That's important because the documents you submit and the activities you're permitted to do in Nigeria depend on the visa you've been issued.

For a tourist trip, Nigeria's current immigration requirements include a passport valid for at least six months, a passport-style photograph, and evidence of a return ticket. Depending on the current application requirements and your circumstances, additional supporting information may also be requested.

Nigeria's Immigration Service currently lists its F5A Tourism Visa as a single-entry visa intended specifically for tourism. Applications are handled through Nigeria's electronic visa system, with the visa certificate delivered electronically after approval.

That electronic approval is something you'll want completed before departure. Don't treat an eVisa as something that can be handled at the airport after you've already started your trip.

Your passport deserves a close look too.

Six months of validity may sound like plenty, but if your passport is getting anywhere near that point, renewing before starting an international visa application can save you from creating unnecessary complications. You also want the information on your visa application to match your passport exactly.

Names, passport numbers, dates of birth, and other details aren't places to improvise.

Traveling for business creates another consideration. Going to Nigeria for meetings, conferences, contract negotiations, trade activities, or other business purposes is different from traveling there for tourism. Actually taking employment in Nigeria is different again.

That's why telling someone, "I'm going to Nigeria," isn't enough information to determine the correct visa.

"I'm going to Nigeria for a two-week vacation" and "I'm going to Nigeria for a six-month work assignment" are two entirely different applications.

Before applying for a Nigeria Visa, know why you're traveling, how long you expect to stay, and what you'll actually be doing while you're there. Gather your supporting documents before beginning the application instead of discovering halfway through that something important is missing.

It's also worth checking the requirements again shortly before applying. Immigration rules, application procedures, and document requirements can change, sometimes without much relation to when you purchased your airline ticket.

Nigeria is one of those destinations where getting the paperwork right is part of planning the trip. Handle it early, double-check everything against your passport, and make sure the visa category matches what you're actually going to Nigeria to do.
