In this paper, we will present a general formalism for constructing thenonlinear charge coherent states which in special case lead to the standardcharge coher- ent states. The suQ(1;1) algebra as a nonlinear deformed algebrarealization of the introduced states is established. In addition, thecorresponding even and odd nonlinear charge coherent states have been alsointroduced. The formalism has the potentiality to be applied to systems eitherwith known "nonlinearity function" f(n) or solvable quantum system with known"discrete non-degenerate spectrum" en. As some physical appearances, a fewknown physical systems in the two mentioned cat- egories have been considered.Finally, since the construction of nonclassical states is a central topic ofquantum optics, nonclassical features and quantum statisti- cal properties ofthe introduced states have been investigated by evaluating single- and two-modesqueezing, su(1;1)-squeezing, Mandel parameter and antibunching effect (viag-correlation function) as well as some of their generalized forms we haveintroduced in the present paper.
