Abstract: We prove that a complete polynomial vector field on $\mathbb{C} ^{2}$ has at most one zero, and analyze the possible cases of those with exactly one which is not of Poincaré-Dulac type. We also obtain the possible nonzero first jet singularities of the foliation $\mathcal{F}_X$ at infinity and the nongenericity of completeness. Connections with the Jacobian Conjecture are established.
