You can't obtain Squirtle or any of its evolutions in Black or White, so you will have to migrate a Squirtle from Pokemon HeartGold or SoulSilver Version. If you don't know how to obtain Squirtle in HeartGold or SoulSilver, you have to beat Pokemon Trainer Red, who is at the top of Mount Silver, and obtain all 16 gym badges. Then, Professor Oak will let you choose one of the Kanto Starters in Pallet Town. Hope this helped!
