  In this paper we study conditions under which, for an inclusion of finite von
Neumann algebras $N \subseteq M$, we have the reduced amalgamated free product
$\ast_N M$ is embeddable into $(R \bar{\otimes} N_1)^\omega$ for some other
finite von Neumann algebra $N_1$, where $R$ is the hyperfinite $\textrm{II}_1$
factor.
