Let $X\subset \mathbb{C}^{n}$ be a domain. You can assume that it is nice (e.g. bounded convex balanced ). Let $\{x_n\}$ be a sequence of points that does not have a limit point in $X$.

Let $D$ be the (unit) disc on the plane.

Is there a holomorphic $\varphi:D\to X$ such that $\varphi(D)$ contains an infinite number of $x_n$?

Of course there are further questions: can we catch all the points? Or maybe all but finite number?

The answer to your quesiton is yes.

In particular in Discs in Stein manifolds containing given discrete sets B. Drinovec Drnovšek proves that given a discrete subset $S$ of a connected Stein manifold $M$ (every domain of holomorphy in $\mathbb{C}^m$ is if this kind) there is a proper holomorphic map $f:D \rightarrow M$ such that $S\subset f(D)$. Moreover if dim $M\geq$3 the map f can be chosen to be an embedding.
