When you get the opportunity to go to the US for work from abroad, then I would say VisaPlace would be your best option to get all your documents in place. My 5 star feedback is based on the help I received from Danielle Grbic as she was really professional, I would straight away ask for Danielle to be in charge of your process. From the time that Danielle took over my case I felt confident that it will go well and at the end it went smoother than expected. On my own I would never have been able to get this internal work transfer done as a L1 visa and was best for the professionals to take charge. After arriving in the US, Danielle was still happy to assist with documents and advise. A huge thanks to Danielle and VisaPlace
