Lack of a 4 year college degree is a problem for a work sponsored green card through the typical path. In addition, for permanent immigration one must prove that there are no qualified and willing US citizens for the position.
There is another option for short term and potential long term stays in the US - L1B and L1A. These are international transfers for a multinational company. Look at the USCIS website for additional information on these visa statuses.
If you are serious, I suggest that you consult a US qualified immigration attorney in the UK to discuss your options in person. THE AILA organization website may assist you in locating an appropriate individual. The USCIS website and the attorney can also explain the options for immigration of green card holder dependent children over 21.
