Considering they were capable of travelling from one dimension to another, it is difficult to determine what was the home dimension (let alone homeworld) of the imps, but they were known to exist in dimensions higher than the 3rd dimension, such as both the 4th and the 5th dimensions. Whether or not any lived in the 6th dimension or beyond is unknown, but they were definitely a rare sight in the 3rd Dimension, where they were generally viewed as supernatural creatures from legends and fairy tales.
Another race of imps resided on the planet Zrfff, which was located in the fifth dimension. This was the homeworld of Mr. Mxyzptlk. Genies and Water Sprites were also races of imps from the fifth dimension.
