a91,
Guys are having a go since it's not good practice to use 'txtspk' in your future life, either online, or in official documents. Nor the moderators like it.
Best of all - the character space on the Internet and this forum is FREE.
If you're not US national or with green card, you're looking for 'F1' visa for aviation - patch for past J1 visa for training and instructing work rights for limited time.
If you are, then you just look for training towards CPL and CFI or CFII certificates and ratings. Plenty information in FAQs. This stuff is done to death, both UK/JAA side and FAA side. Besides, any US flight school's website would give an outline of the training and what it entails.
