You do not require a visa for a commercial if the training is incidental to your visit, ie vacation it does not require anything more than you require for a vacation. The issue is that because it us your initial lfaa licence you will need tsa which most people then interpret as requiring a visa too.
That said, its all about circumstances and individuals. If you have a few hundred hours and already got complex/ high performance and current so only need say 8 hours then its quite credible to do that within a two week vacation, especially if you are with your partner or on a business trip or whatevet. If you need say 25 hours and are clearly making a pilgrimage to a residential course at a flight school for a month youd be wise to be on an m1 visa.
My personal experience is that there is no issue with commercial training or indeed entering for a private check ride on visa waiver, based on several entries.
A 61.75 is worth having if you just want to do ppl rental, if you have any further ambition forget the 61.75 and do the faa ppl checkride and written, youll know you are up to the required standard and have the necessary knowledge to enjoy flying in the usa too.
If you hold a cpl already I just posted advice in the tsa thread also on this, depending on what else you hold
