Weather at the moment
Weather all year round
Chicago is constantly influenced by its proximity to Lake Michigan and enjoys a continental climate. The wind that blows fairly regularly over the city looks like a refreshing breeze on hot summer days, but can be cruelly striking on cold winter days. Chicago temperatures are generally extreme in winter (sometimes as low as -25°C and almost always snow) and in summer (up to 40°C in July)
If you book in advance, you can find a hotel in Chicago for 90-100 US$, in any season. Be careful, during the convention period, room prices can be multiplied by three. We eat well and easily for less than 20 US$. On the other hand, public transport is more expensive than in France (around US$2.50 per ticket). Admission to Chicago museums is about US$12.
France is still part of the Visa Waiver Pilot program, which allows all French nationals to enter the United States without a visa for a stay of up to 90 days. All you need to get into Chicago is to have
A valid biometric passport.
A non-refundable round-trip ticket to the United States and not intend to extend his/her stay.
The ESTA form completed on the Internet at least 72 hours before departure and payment of the US$14 fee that accompanies this form (https://esta.cbp.dhs.gov).
Finally, for any stay longer than 90 days, the visitor must be in possession of a visa. Several types of visas exist (student, work, etc.), but they are all quite difficult to obtain. For more information on the type of visa to apply for and the procedures to follow, visit the website of the U.S. Embassy in France .
While the risk of illness is relatively low during a stay in the United States, medical care is extremely expensive. Chicago's medical infrastructure is, however, excellent, as in the rest of the country. In case of emergency, you must call 911 on any phone, even mobile phones that no longer have units will work in this case. Or go to the nearest emergency centre. You will be taken care of all the more quickly if you provide proof of creditworthiness (credit card or insurance). No vaccination certificate is required to enter the United States. Persons undergoing medical treatment will need a prescription to prove that they are not importing illicit products. The only precautions to take are mosquito repellent in summer - Lake Michigan is infested - and equipment adapted to the extreme winter cold.
