Just save lorelei at four island in icefall cave then wait a few minutes by training your Pokemon then go to the league and they should let you go in. Warning: They are stronger and have new Pokemon, good luck.
Neither league exist in LeafGreen. Only the Indigo League is programmed into the game. In chronological terms the Orange League comes after the Indigo League and then the Johto League.
Pokemon indigo isn't a game as far as im concerned, but assuming it is like leaf green, fire red, yellow, blue, and red, you must beat the Pokemon league and some other task, i cant remember what that is....
Beat the Pokemon League on DS. Then insert Leaf Green and select migrate from 'Leaf Green'.
in the Pokemon league!

In his cottage at route 25.
I do not know which game you mean so i will say all : Leaf green: Indigo plateau (left from virdinian city) Fire red: Indigo Plateau (left from virdinian city) Emerald: Evergrand City (Near mossdeap) Saphire: Evergrand City (Near mossdeep) Ruby: Evergrand city (near mossdeep) Hope this helped :) (Ive played Emerald and leaf green - Leaf green and fire red are the same as are ruby, emerald and saphire)
White light form the sun is made up of :-Red, Orange, Yellow, Green, Blue, Indigo and Violet colored light (as you see in a rainbow)When this white light hits a leaf, all the colors exceptGreen are absorbed by the pigments in the leaf. The Green light is not absorbed and this is reflected to your eyes so that leaves appear green.

The green part of the leaf is green because of the chlorophyll inside

You beat all the gym leaders and get all badges then you need SURF, CUT and STRENGTH and go through the victory lane and you will get there
