The operations will be dealt with by the share registry and your broker automatically, if your required to do anything you will be sent mail so I wouldn't worry.
I'd also imagine the company will release guidance on all important dates once the information becomes available. No need to worry if your a long term holder, just sit tight and the shares will pop up in your international holdings account in good time hopefully at a much better market cap!
I would note that the company will likely consolidate the shares so 10 shares will become 1 share for example. This wont effect the value of your holding. The NASDAQ requires a price of minimum $3 to list I think so I reckon a 100 for 1 consolidation is probably likely.
Example you hold 1000 shares now at 4c you will hold 10 shares on the Nasdaq at $4.
Hope this is helpful mate!
Cheers
