Stir together potatoes and flour. Stir in eggs, green onions, and salt; blend well.
Pour vegetable oil to a depth of 1/2 inch in a large heavy skillet. Heat to 350°. Drop potato mixture by tablespoonfuls into hot oil; gently flatten latkes with back of a spoon. Fry, in batches, 3 to 4 minutes on each side or until golden. Drain on paper towels. Serve immediately.
