Hi,

The Bachelor degree in India and United Kingdom is for three years and that in USA is for four years. Both the degrees are considered equivalent and both the degrees are same as similar number of credits are covered in the coursework. As far as master degree is considered, the one year master degree of UK is not considered valid in many countries including India where you will have to do another master to be considered a master degree holder. Similarly USA also has such implications.

I hope this helps.

All the best.
