Miller, who is preparing for Scotland's friendly with Luxembourg on Wednesday, has confirmed that he would be open to a loan so he can keep himself fit ahead of World Cup qualifiers in March.
"I don't want to be taking the time off, so this is another week's training and a game for me," he said. "Nobody has been in touch [about a loan].
"There are a lot of hurdles to be crossed between leagues, teams, the MLS etc for it to happen. It's something I've not thought too much about, but I'm not too keen to take the time off so if something came up I'd look into it.
"Our season will have started [by the time of the March qualifier]. It's in a similar area to the September qualifiers here, because I'll have had three or four games under my belt going into them. Our first league game is March 2.
"It's a case of not being too fussed and of trying to find someone willing to take you where you're going to get games. Even if it's not starting every week, as long as you're training towards it and taking part just to keep you ticking over, that would be important.
"Here or down south, it doesn't really matter where I go as long as it means I'm ready for the games in March."
