Is there a crossover deadline for bills in the US Senate?

Not sure what you mean by "crossover." Do you mean a certain time that bills have to come out of the House to be considered by the Senate, or get out of the Senate to go to the House?

AKAIK, there is no deadline set in the Constitution. A bill could, Constitutionally, be introduced 5 minutes before midnight on the day before the new batch of Senators takes their oath. That being said, I'm sure there's rules in both chambers for consideration of bills, and when they should be submitted. Don't forget, the bills have to go to committees and subcommittees to be fooled around with before the full chamber gets to fool around with them and vote on them.

Yeah I meant crossover from one chamber to another like many state legislatures.

Also, aside from revenue bills (I forget the exact Constitutional terminology), which must start in the House, there's no requirement that any bill originate from a specific chamber. Either chamber can start any bill whenever they want. And neither chamber is under any obligation to consider any bill passed by the other. So, for example, the Senate can pass all the AWB bills they want, and the House is free to ignore them.
