There are several phases involved in applying for a USA visa, depending on whether you are looking for a B1/B2 tourist/business visa, an F-1 student visa, or an H-1B work visa. The process typically begins with filling out the online DS-160 form, paying for the visa, scheduling an interview at a U.S. embassy or consulate, and submitting the required documents, including your passport, photo, and proof of purpose of visit. During the visa interview, applicants must demonstrate their intention to return to their home country and meet financial conditions.Because every visa category has different requirements, it is essential to ensure that all documentation is accurate and complete in order to avoid delays or denials.
