However, depending on the country, the prepared documents will be different, may be simpler, may be more complicated, can be submitted online or in hard copy, use fingerprints or an interview.
To make your trip abroad easier and faster, HT has visa services for the US, Canada, Europe, UK, and Australia. Please contact HT for more detailed advice!
