1. Congress may submit a proposed constitutional amendment to the states, if the proposed amendment language is approved by a two-thirds vote of both houses; or
2. Congress must call a convention for proposing amendments upon application of the legislatures of two-thirds of the states (i.e., 34 of 50 states); and
3. Amendments proposed by Congress or convention become valid when ratified by the legislatures of, or conventions in, three-fourths of the states (i.e., 38 of 50 states).
