Doha to Houston (DOH–IAH) — Airlines, Schedules & Connections

Qatari passport holders need a visa to enter the United States. Qatar is not in the Visa Waiver Program, so ESTA is not available. Apply for a B1/B2 visitor visa at the US Embassy in Doha. The application fee is $185 (non-refundable). Steps: complete the DS-160 form online at ceac.state.gov, pay the fee, schedule an interview at the embassy, and attend in person with your passport, DS-160 confirmation, photo, and supporting documents (bank statements, employment letter, travel itinerary).

Interview wait times at the Doha embassy run 2 to 6 weeks depending on the season. B1/B2 visas are typically issued for 10 years with multiple entries, allowing stays of up to 180 days per visit. The CBP officer at the US port of entry determines the actual admission period (usually 90 to 180 days stamped on your I-94). Have your hotel address, return ticket, and itinerary ready. Fingerprints and a photo are taken at the immigration counter.

Direct flights from Doha to the US run on Qatar Airways: New York JFK (about 13 hours 30 minutes), Washington Dulles (about 14 hours), Dallas-Fort Worth (about 15 hours 30 minutes), Houston (about 16 hours), Los Angeles (about 16 hours 30 minutes), and Chicago (about 14 hours 30 minutes). The US uses the US dollar, trading at roughly 0.27 USD per QAR 1 (or 3.64 QAR per $1). No mandatory vaccinations. Global Entry ($100 for 5 years) expedites CBP processing for approved travelers using kiosks. Apply at ttp.cbp.dhs.gov and interview at a Global Entry enrollment center.

Ride-hails pick up at the designated Rideshare zones outside baggage claim on the lower level.IAH has five terminals (A–E) connected by an underground tunnel with trams. Terminal D handles international arrivals. Rental car agencies are in a consolidated facility adjacent to Terminal C; a free IAH Connector bus runs between terminals and the rental car center.

Humid subtropical climate. Hot, humid, and wet for much of the year. Summers are brutal (33–38°C) with high humidity and near-daily afternoon thunderstorms. Severe storms with hail and high winds regularly cause ground stops from April through September. Houston's flooding risk is significant. Heavy rain events, including tropical system remnants, have flooded airport roads, cutting off surface access even when the airport itself remains operational.

Winters are mild (5–18°C) with occasional ice storms. These are rare but highly disruptive when they occur. Hurricane season (June–November) requires monitoring for Gulf storms. October through March has the best flying weather.
