Spoilers have come and gone but one question remains unanswered – when will "House of Cards" season 4 return to Netflix? The streaming giant still has not penned a premiere date for the show so at the moment, it is up to fans to figure out how long they'll have to wait for Frank Underwood's return.

Production for the new season of the political drama is well underway. In fact, Baltimore Sun has reported that the crew was in the Baltimore area yesterday in search for a number of "new faces" and extras to take part in some of the scenes.

"Casting directors are looking for reporters, photographers, videographers, and boom operators to work on the upcoming scene," the casting call posted in Project Casting reads. No details on the said "House of Cards" season 4 scene were mentioned.

As for the premiere date of the new season, Fansided believes that Frank Underwood will return by March. This is based on how Netflix chooses the premiere dates of the previous seasons. The site discovered that these said release dates follow a one-year and 13-day gap.

The show debuted back in Feb. 1 in 2013 while the second season dropped on Netflix by Feb. 14 last year. The third season followed suit as the show made its return by Feb. 27 this year. If Netflix is not planning on changing things up on the schedule of the series, it is highly likely that "House of Cards" season 4 will be out Mar. 11, 2016.

While it seems a pretty solid deduction, it won't be official unless Netflix says it is. At the moment, only time will tell. But when the show returns, fans will finally be able to check back in on Frank, who is struggling to move on from being left by his wife in the middle of his preparation for the presidential election.
