Official visa page

Weather

April is one of Tampa's most comfortable months, with afternoon highs near 28 °C / 82 °F, overnight lows around 18 °C / 65 °F and moderate humidity that builds through the month. Rainfall averages roughly 60–65 mm across about seven rain days, falling almost entirely as short, intense afternoon thunderstorms rather than all-day rain. Pack lightweight business casual clothing, a light layer for heavily air-conditioned session rooms, a compact umbrella and sun protection for the Riverwalk walks between hotels and the convention centre.

Plan for the climate

Check temperatures and pack accordingly

Venue connectivity

Downtown Tampa has strong 5G coverage from AT&T, T-Mobile and Verizon, and the Tampa Convention Center plus most downtown hotels provide complimentary Wi-Fi in lobbies and meeting areas. International visitors should activate a roaming plan or buy a travel eSIM (Airalo, Holafly or a T-Mobile prepaid plan) before departure, as US prepaid SIMs require an unlocked handset and photo ID. US power is 120 V with Type A/B plugs, so bring a converter for European or Asian devices.

Ride-hailing

Taxis

Public transit

Car rentals

Cultural notes

Useful information to help you have a smooth and respectful visit.

Tipping

Tipping is expected: 15–20% on restaurant bills, USD 1–2 per drink at the bar, USD 2–5 per night for housekeeping and 10–15% for taxi or ride-hail rides.

Business dress and greetings

Business casual is the norm for technical sessions, with jackets common among exhibitors and supplier executives. A firm handshake and first names are standard; business cards are exchanged freely at booths.

Local flavour

Tampa blends Cuban and Latin heritage with a Gulf Coast waterfront — Ybor City, ten minutes from downtown, is the place for cigar shops, live music and a classic Cuban sandwich.

Practical guides

Visitor & Exhibitor Essentials

Everything needed to arrive prepared, navigate the event, and make the visit productive.

Flights

Destination: TPA

Book flights to TPA when possible for the shortest transfer to the venue; compare PIE only if fares are materially lower.

Visa

Most foreign nationals need a US visitor visa for business (B-1) to attend the conference and heavy equipment expo; attending a business convention or conference is an approved B-1 activity. Citizens or eligible nationals of Visa Waiver Program countries can instead travel on an approved ESTA for stays of 90 days or less.

Estimated cost: Varies by visa type and nationality (check official site).

Processing: Varies by nationality and consulate; apply several weeks to several months ahead because interview appointment slots can be limited.

Carry conference registration confirmation and any organiser invitation letter to your visa interview; business travel may also cover attending business meetings and negotiating contracts.

Plan your trip

Planning

Best day to visit: Monday 5 April 2027 (Day 2)

Day 2 combines a full technical paper and standards programme with an exhibition hall that is fully open and staffed, while the Sunday registration rush has passed — so visitors can move between sessions and supplier booths without queuing. Tuesday 6 April is the fallback if travel lands late, but Monday gives the best balance of technical content and exhibitor access.

Confirm passport validity and US visa or ESTA status — Book a B-1 visa interview early if required; check ESTA eligibility for Visa Waiver Program nationals before booking travel.

Compare and book flights into Tampa International Airport (TPA) for 3-7 April 2027 — Allow arrival on 3 April to collect your badge before the 4 April opening.

Book a downtown hotel near the Tampa Convention Center — Embassy Suites by Hilton and Hotel Tampa Riverwalk are walkable; Westshore hotels need a car or shuttle.

Complete online registration at iiar.org — Choose full conference or Monday-only registration; end users and first-time attendees receive member pricing.

Download the conference programme and mark sessions — Shortlist technical papers, white papers, workshops and panels that match your plant or project.

Pre-schedule meetings with exhibitors and peers — Use the exhibitor list to request meetings ahead of the three-day expo hall opening.

Shortlist ammonia and natural refrigeration suppliers — Note the heavy equipment demos and component makers you want to benchmark.

Plan local transport around downtown Tampa — Downtown is walkable and the TECO Line Streetcar links nearby districts; check HART routes.

Arrange parking or ride-hail for driving days — The Tampa Convention Center garage at 141 E. Brorein Street charges an event rate of $5 to $50; daily non-event parking is capped at $18.

Pack for warm, showery April weather — Bring lightweight business casuals plus a rain jacket for brief afternoon showers.

Prepare business cards, specs and meeting documents — Load technical drawings and specs on a laptop or tablet for on-stand discussions.

On arrival, collect your badge and confirm session rooms — Pick up your badge at the IIAR registration desk and check the daily schedule.
