Does your EASA license allow you to fly a Seneca IFR in your home country? Under the FAA system getting a B737 type without any prior ME time would grant you a ME rating valid in any MEL airplane under 12,500 pounds max gross TO weight. The 61.75 certificate requires the holder to obey all restrictions on the underlying license. So for example if it is an Australian license with a CE-172 rating their FAA certificate would say SEL but they would not be able to fly a PA-28 even though there is no FAA limitation.
