Before coming to the United States to study, you must obtain an F-1 student visa from the US Embassy in your country. Under NO circumstances should you plan to enter the USA with a B-2 tourist visa. Any other immigration questions should be directed to the Director of MSIA in a timely manner. The weather from January to the end of March can be very cold. However, it will seem colder due to the humidity in this region.
Warm clothing is required.
However, it is also a rainy season. Shoes that will keep your feet dry are highly recommended. Again, it is the humidity that makes the heat feel worse. For these months, it will be necessary to have cool clothing, like shorts and thin shirts. There is sudden rain in mid-afternoons, so an umbrella should be carried for these times.
