The Real Madrid midfielder insists: "Will playing in America have an adverse effect on my England chances? I hope not. Physically I will be fine. I will still be as good as I am today. That is not going to be a problem.
"Travelling is not going to be a problem because I will travel from anywhere to play for my country so we will see. I haven't worked out schedules but I am sure it can be done nearer the time.
Beckham received a hero's welcome from the 88,000 crowd when he returned against the Brazilians who only denied England victory with an injury-time goal from substitute Diego.
The former Manchester United star said: "It was very emotional. To have a response like that was incredible.
"It was definitely much more than I ever expected but it has been nice to have had the support of the public and the fans throughout my career.
"Friday night was amazing for me, not just for myself but the family as well and nothing will ever take away the pride I feel when I put on that England shirt."
Beckham added: "Did I think I would come back with England? I am a positive person so I always believed I would get another chance but there was a doubt in my mind.
"Now I hope I am here for the duration but I have always felt throughout my career that I've had to fight for my place and that's what I will do - and will carry on doing.
"I am going to take each game as it comes."
