"The United States, which is not a signatory to the 1954 Convention on the Status of Stateless Persons or the 1961 Convention on the Reduction of Statelessness, is one of a small number of countries that allow their citizens to renounce their citizenship even if they do not hold any other "

There is no overall solution that fits for all.
