Plan your trip

Visa & entry documents

Check the latest visa requirements and entry guidelines before travelling.

Visa not required

ATA Carnet: check with organiser

Official visa page

Weather

Chicago in late November: cold and grey with average highs near 8 C and lows near 0 C; lake-effect wind off Lake Michigan makes the Magnificent Mile corridor feel colder than the thermometer reads, and light rain or the season's first snow flurries are possible.

Plan for the climate

Check temperatures and pack accordingly

Venue connectivity

US mobile networks (Verizon, AT&T, T-Mobile) cover the Magnificent Mile and downtown Chicago; visitors on international SIMs should confirm roaming or pick up a US prepaid eSIM/SIM for the AIC week. Wi-Fi is standard in downtown hotels; the Chicago Marriott Downtown Magnificent Mile lists Wi-Fi as a paid amenity, so conference attendees may prefer a US data plan for email and abstract browsing.

Cultural notes

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

Business dress

Immunology faculty and industry scientists typically wear business casual to smart casual at AIC sessions; poster sessions and trainee mixers are more relaxed. Bring a warm coat, hat and gloves for the walk between hotels and the Magnificent Mile venue.

Tipping and payments

Chicago runs on US tipping norms: 18-20 percent at restaurants, 1-2 USD per drink at bars, and a small tip for housekeeping. Cards and mobile wallets are accepted almost everywhere; keep a few dollars for valet and coat check.

Arrival and registration

Collect your badge at the AIC attendee registration desk on arrival day; the conference opens Friday evening and runs through the weekend, so plan to arrive before the first Friday session if you are presenting a poster or abstract.

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

Flights

Destination: ORD

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

Visa

Most overseas immunologists travelling to AIC 2026 in Chicago need either a US B-1 business visitor visa or entry under the Visa Waiver Program (ESTA) if they hold a VWP-country passport; US citizens and residents need no visa. Carry your AIC registration confirmation, abstract or invitation letter and hotel booking.

Estimated cost: B-1 visa fee is set by the US Department of State; ESTA charges a separate fee for VWP travellers. Confirm the current amount on travel.state.gov before paying.

Processing: B-1 appointment and issuance timelines vary by US embassy or consulate; ESTA under the Visa Waiver Program is usually decided within 72 hours, so apply well ahead of the 20-22 November 2026 conference.

Check dhs.gov for the Visa Waiver Program country list before assuming ESTA applies. Bring the AIC registration confirmation, abstract acceptance or invitation, and downtown Chicago hotel booking to the consular interview or US port of entry; USCIS and travel.state.gov publish the current B-1 rules.

Ride-hail: Ride-hailing apps are commonly used in Chicago; confirm local availability before travel.

Public transit: CTA 'L' and bus routes cover the Magnificent Mile and River North: the Red Line stops at Chicago and Grand, and downtown bus routes serve Michigan Avenue directly, giving AIC attendees an easy fallback when hotel shuttles or rideshares are slow during Chicago's evening rush. Fares are tap-and-go with Ventra; rideshares and walking are practical for hotels within the Magnificent Mile / Streeterville cluster.

Weather

Plan and pack for the event climate.

Month: November 2026 (AIC 20-22 November 2026, Chicago)

Temperature: Average daily high around 8 C (46 F), average low around 0 C (32 F); occasional days dip below freezing, especially late in the month

Seasonality: November is one of Chicago's wetter, greyer months; expect around 8-10 rainy days, overcast skies and a chance of the season's first snow flurries near the end of the month.

Packing: Pack a warm, wind-resistant coat, sweaters, a scarf, hat and gloves for the lakefront wind, plus a compact umbrella and water-resistant shoes for wet sidewalks. Layers help because hotel conference rooms, the venue and downtown restaurants are heated well above outdoor temperatures.
